v0.5.0: fix update-check repository URL (inherit workspace repository)

The About-tab "check for updates" returned "repository URL not configured at build time" because the http-api crate didn't inherit the workspace `repository` field, leaving CARGO_PKG_REPOSITORY empty. Add `repository.workspace = true` so the Gitea releases API URL derives correctly, and strengthen the unit test to assert the URL is present. Caught by the v0.5.0 container smoke test before publish.

v0.5.0: Wake-on-LAN, webhook notifications, Advanced tab, login logo, update check

+//! This module owns only the *configuration* (validation + persistence

+//! chat providers, SMTP for email — lives in the http-api crate, which
+//! already carries an HTTP client and the SMTP dependency. Keeping the
+//! network I/O out of `core` matches how `BrandingStore`/`SsoStore`
+//! stay pure config stores.
+//!
+//! Secrets note: the SMTP password is persisted in `notify.json`
+//! alongside the rest of the config (0644 like the other state files).
+//! It is never echoed back through the API — the snapshot used for the
+//! GET response blanks it (see `Self::redacted`).

+//! Wake-on-LAN.
+//!
+//! v0.5.0: from the Hosts tab, an operator can wake a bound machine.
+//! WoL is a "magic packet" — six `0xFF` bytes followed by the target
+//! MAC repeated sixteen times (102 bytes total) — broadcast on the
+//! local segment. The NIC's WoL logic matches the repeated MAC and
+//! powers the board on.
+//!
+//! ## Why this is trivial and safe in our container
+//!
+//! - It's a single UDP datagram to a broadcast address. No privileged
+//!   *local* port is needed (we bind an ephemeral source port); the
+//!   destination port is conventionally 9 (discard) or 7 (echo), and
+//!   nothing actually listens there — the magic is in the payload, not
+//!   the port. So WoL works without any extra capability.
+//! - We send to the limited broadcast `255.255.255.255` (stays on the
+//!   local link) and, when the caller knows the server's own subnet
+//!   broadcast, to that too — directed broadcast reaches the right VLAN
+//!   even when the host bridges multiple segments.
+//!
+//! ## Limits
+//!
+//! WoL only crosses L2. If the target is on a different subnet than the
+//! OpenPXE host, the intervening router must be configured to forward
+//! directed broadcasts (most aren't, by design). For the common case —
+//! OpenPXE and its PXE clients on the same VLAN — the limited broadcast
+//! is enough.

-//! NFS share manager.
-//!
-//! Lets an operator mount a remote NFS export as an ISO source instead of
-//! uploading every ISO into the container's PVC. Supports NFSv3 and
-//! NFSv4.1 — the two versions the user explicitly asked for.
-//!
-//! ## How it works
-//!
-//! 1. Operator submits a mount spec via the Storage tab:
-//!    `{ server: "10.0.0.20", export: "/srv/isos", version: "v41" }`.
-//! 2. We slugify a stable id, mkdir `<work_dir>/nfs/<id>/`, then shell out
-//!    to `/bin/mount -t nfs -o vers=...,ro,nolock server:export local`.
-//! 3. On success we walk the mount point looking for `*.iso` files and
-//!    register each one with the `IsoStore` as an external source — same
-//!    introspection pipeline as a web upload, but no sha256 (the bytes
-//!    live on a remote machine; hashing them would suck them through the
-//!    network on every restart).
-//! 4. On failure we record `last_error` on the spec and persist anyway
-//!    so the UI can show a row in red rather than silently dropping it.
-//!
-//! ## Operational notes
-//!
-//! - Mounting NFS inside a container needs `CAP_SYS_ADMIN` and the
-//!   `nfs-common` package. The default image ships these (see Dockerfile).
-//! - On OpenShift, the SCC must allow `CAP_SYS_ADMIN`. The bundled SCC
-//!   doesn't — operators have to opt in by switching to a more privileged
-//!   SCC or running NFS mounts as a CSI driver outside the pod.
-//! - Mount commands are issued sequentially under a single mutex to avoid
-//!   `mount` racing on the same target dir.
-//!
-//! ## Persistence
-//!
-//! Mount specs (without runtime state) live at `<work_dir>/nfs.json`,
-//! re-mounted on startup. Mounts that fail to come back online keep their
-//! spec and their `last_error` so the operator sees what happened.

-//! Operator-logo compositor for the iPXE menu.
+//! PXE boot-menu background compositor.
 //!
-//! The brief: match iVentoy's polished centered-logo PXE chrome with
-//! whatever raster the operator drops onto Settings → Branding. A wide
-//! wordmark, a portrait stack, a square monogram — all three should
-//! land in roughly the same place on the boot screen.
+//! The brief (v0.4.69): match iVentoy's polished graphical PXE screen.
+//! iPXE built with `CONSOLE_FRAMEBUFFER` + `IMAGE_PNG` paints a PNG to
+//! the framebuffer via `console --picture`, then draws the text menu on
+//! top (the console's default background colour is rendered transparent
+//! so the picture shows through the menu's blank cells). So what we
+//! produce here is a **full-screen 1024×768 background**, not just a
+//! floating logo:
 //!
-//! Approach: decode the operator's upload, fit it into a fixed
-//! 1024×768 canvas with the logo horizontally centered and pinned a
-//! short margin from the top, re-encode as PNG, return the bytes. iPXE
-//! built with `IMAGE_PNG` paints the result via `console --picture`.
+//!   - a solid dark field (matches the WebUI dark theme so the product
+//!     feels consistent from browser to bare metal), with
+//!   - the operator's uploaded logo composited across the top, leaving
+//!     the lower ~two-thirds clear for the iPXE menu text.
 //!
-//! The 1024×768 size matches the default VESA framebuffer iPXE picks
-//! on most BIOS/UEFI consoles. Operators uploading 4K logos get
-//! correctly downscaled; tiny icons get drawn at their native size,
-//! centered, with transparent margins.
+//! When no custom logo is uploaded we still return a designed
+//! background — a dark field with a centered "rainbow-horizon" disc
+//! echoing the bundled OpenPXE mark — so the boot screen is graphical
+//! out of the box. This replaces the old ASCII wordmark entirely.
 //!
-//! We deliberately don't ship `resvg` for SVG support — keeping the
-//! dependency surface narrow matters more than supporting SVG-only
-//! brand assets. The WebUI's logo stays SVG-native (the browser
-//! rasterizes it); the PXE menu wants a raster regardless.
+//! iPXE does **not** scale pictures (confirmed against the decoder
+//! source): the image is painted at native pixel size and the firmware
+//! picks the smallest video mode that fits. 1024×768 is the universal
+//! safe mode, so we pin the canvas there. Operators uploading a 4K logo
+//! get it downscaled to fit the top band; tiny icons paint at native
+//! size, centered.
+//!
+//! Input formats: anything the `image` crate decodes with our enabled
+//! features — PNG, JPEG, WebP, GIF. iPXE itself only consumes PNG, so
+//! we always *emit* PNG regardless of what the operator uploaded; a
+//! WebP logo is transcoded here transparently.

+# PXE menu theme — research for next-release follow-up
+
+Status: queued. v0.4.63 keeps the ASCII-banner fallback + `console --picture`
+compositor wired; this note captures the design for the menu-theming work
+that lands once iPXE rebuilt with `IMAGE_PNG` is published.
+
+## How iVentoy actually does it
+
+iVentoy is closed-source for its menu, but the supporting bits are
+public at https://github.com/ventoy/PXE — a vanilla iPXE snapshot
+(`iPXE/ipxe-bd13697`) used to produce the loader binaries iVentoy
+serves over TFTP (`pxeboot.efi`, `iventoy_loader_16000`,
+`iventoy_loader_16000_uefi`).
+
+The graphical menu itself is rendered by iPXE's framebuffer console
+with a baked-in PNG background via `console --picture` — same
+primitive OpenPXE already uses in `crates/http-api/src/ipxe_script.rs`.
+Evidence:
+
+- The iPXE build in `ventoy/PXE` is configured with `CONSOLE_FRAMEBUFFER`
+  + `IMAGE_PNG` + `CONSOLE_CMD` (the three flags `console --picture`
+  needs).
+- iVentoy issue #11 confirms "iventoy using default 1024x768"; users
+  report 800x600 / 1024x768 / 1280x720 / 1280x1024 / 1920x1080 as
+  selectable resolutions from the iVentoy web UI **Configuration tab**,
+  not via EDID auto-detect. iPXE has no EDID parsing; the daemon writes
+  a resolution-tagged script per boot and serves the matching PNG.
+- iVentoy docs explicitly state both Free and Pro editions **do not
+  support** modifying the boot background/title — it's baked into the
+  shipped PNG assets.
+- Chrome is iPXE's native `menu` / `item` / `choose` widgets (single
+  highlight bar, no borders) painted on top of the PNG, with margins
+  set via `console --left/--right/--top/--bottom` to keep the text off
+  the logo. Not GRUB, not syslinux — UEFI iVentoy uses iPXE's
+  `snponly.efi` / `pxeboot.efi`, and `--picture` does work under UEFI
+  GOP despite older folklore.
+
+Do not conflate this with Ventoy-USB, which is a separate codebase and
+uses GRUB2 themes (`theme.txt`, `background_ventoy.png`, `select_c.png`).
+
+## Rust ingredients to replicate / surpass
+
+Most of these already exist in the workspace.
+
+1. **Compositor (extend, don't replace)** — extend
+   `crates/iso-store/src/pxe_logo.rs` to emit per-resolution PNGs
+   (1024x768, 1280x1024, 1920x1080 as the v1 set). `image` +
+   `imageproc` crates handle scaling; `ab_glyph` / `fontdue` for raster
+   text (subtitle, hostname, version). One source SVG/logo, three to
+   five rendered PNGs cached on disk.
+2. **Script generator** — `ipxe_script.rs` already emits
+   `console --picture … || console`. Add a `?res=` query param (or
+   per-MAC client hint persisted in `hosts.json`) and serve the matching
+   PNG plus matching `console --x --y` line. Keep the text-console
+   fallback already in place.
+3. **Resolution selection** — iPXE exposes `${vesa-x}` / `${vesa-y}` on
+   BIOS; UEFI side we can probe firmware vars at chain-time. The simpler
+   v1 is a "low-res / hi-res" toggle in Settings plus a per-host
+   override — mirrors iVentoy's UX, no kernel helper needed. True EDID
+   parsing is overkill for the first cut.
+4. **Chrome upgrades over iVentoy** — iPXE menus are limited (single
+   highlight, no borders). To look distinctly cooler without leaving
+   iPXE: paint border / title / footer **into the PNG**, leave a window
+   in the middle, then `console --left/--right/--top/--bottom` to inset
+   the iPXE menu exactly into that window. ASCII box-drawing inside the
+   menu remains fragile (iPXE mangles non-ASCII on some builds — already
+   noted in `ipxe_script.rs`).
+
+## Recommended architecture for the next OpenPXE release
+
+- Build a `pxe_theme` module beside `pxe_logo.rs`: takes operator logo
+  + theme tokens (accent colour, title, footer) and renders a layered
+  PNG (background gradient → framing chrome → logo → title bar → footer
+  with `${hostname}` / `${version}` / `${ip}`) at the three target
+  resolutions. Cache by hash of inputs.
+- Serve at `/branding/pxe-menu-{w}x{h}.png`. Default 1024x768; expose a
+  Settings dropdown.
+- In `ipxe_script.rs`, emit
+  `console --picture …/pxe-menu-1024x768.png --left 80 --right 80 --top 180 --bottom 60 || console`,
+  then the existing `menu` / `item` / `choose` block — text now lands
+  inside the framed window.
+- Compile iPXE with `CONSOLE_FRAMEBUFFER`, `IMAGE_PNG`, `CONSOLE_CMD`,
+  `CONSOLE_VESAFB` (BIOS) and `CONSOLE_EFIFB` (UEFI). The v0.4.61 image
+  attempted this in-Docker via QEMU emulation and hit `cc1` segfaults.
+  The follow-up will use a Gitea Actions runner pinned to native
+  `linux/amd64` (an Unraid host already exists for this).
+- Stretch goal: a second "theme pack" that ships a layered PNG with
+  subtle scanlines / grid — iPXE can't animate, but a well-designed
+  static composite beats iVentoy's plain centered logo handily.

+# Build PNG-enabled iPXE binaries from source.
+#
+# Why from source: the official boot.ipxe.org binaries (and the
+# Debian-packaged ones) are NOT built with CONSOLE_FRAMEBUFFER +
+# IMAGE_PNG + CONSOLE_CMD, so `console --picture` is a no-op on them —
+# you can't paint a graphical boot-menu background. iVentoy solves this
+# by shipping its own iPXE build with exactly those three flags; we do
+# the same, from upstream iPXE, with a thin auditable config delta
+# (deploy/ipxe/local/{general,console}.h).
+#
+# Why a real cross-compiler instead of QEMU: building amd64 iPXE by
+# emulating an amd64 gcc under QEMU on an arm64 host intermittently
+# segfaults cc1 (the reason this was stuck for ~8 releases). Running a
+# NATIVE arm64 gcc that cross-targets x86_64 (CROSS_COMPILE=
+# x86_64-linux-gnu-) sidesteps emulation entirely — the compiler is a
+# native binary, it just emits x86_64 objects. This stage is meant to
+# run on $BUILDPLATFORM (the native builder arch), NOT the emulated
+# target platform.
+#
+# Outputs (into $DEST), using the filenames OpenPXE's arch mapping
+# expects:
+#   snponly.efi   x86_64 UEFI, PNG-enabled
+#   ipxe.efi      x86_64 UEFI, PNG-enabled (bundled drivers)
+#
+# We build ONLY x86_64 UEFI, always via the x86_64 cross toolchain
+# (`x86_64-linux-gnu-gcc`). That's deliberately host-arch-agnostic: it
+# works whether this stage runs on an arm64 Mac builder or an amd64 CI
+# runner, because the cross compiler runs native and emits x86_64
+# either way. Building arm64-efi or BIOS here would re-introduce a
+# dependency on the host arch (native arm64 build) or a 32-bit multilib
+# toolchain — so those arches keep their upstream-fetched (no-PNG)
+# binaries and fall back to the menu's clean `|| console` text screen.
+# Modern PXE clients are overwhelmingly x86_64 UEFI, which get the full
+# graphical background.
