v0.4.69: PNG boot-menu background (iPXE built from source), NFS AUTH_SYS, FleetDM logo

Three things, headlined by the long-blocked graphical PXE menu.

## 1. Graphical PXE boot background — the iVentoy feature, finally

iVentoy paints a PNG background on the PXE screen using stock iPXE
built with CONSOLE_FRAMEBUFFER + IMAGE_PNG + CONSOLE_CMD; the public
iPXE binaries omit those, so `console --picture` is a no-op on them.
We now build our own iPXE from upstream with that thin config delta
(deploy/ipxe/local/{general,console}.h).

The 8-release blocker was cc1 segfaulting when an amd64 gcc ran under
QEMU emulation on the arm64 build host. Fix: a new `ipxe-build`
Dockerfile stage pinned to $BUILDPLATFORM (native arch — no emulation)
that cross-compiles x86_64 iPXE with CROSS_COMPILE=x86_64-linux-gnu-.
The compiler runs native and emits x86_64. Validated end-to-end:
png.o + fbcon.o + pixbuf.o all compile and link (confirmed via the
linked-ELF symbol table, not just strings), ~112s, no segfault. Host
tools needed libc6-dev (dropped by --no-install-recommends; without
it the native host compile falls through to iPXE's freestanding
headers and dies on bits/stdint.h — fixed).

Server side:
- pxe_logo.rs is now a full-screen background compositor: a dark field
  (matching the WebUI theme) with the operator's uploaded logo across
  the top, or — with no upload — a default OpenPXE rainbow disc drawn
  with pure pixel math (no font/SVG deps). Always 1024x768 (iPXE
  doesn't scale; this is the universal mode). WebP/JPEG/GIF/PNG in,
  PNG out (iPXE only eats PNG).
- /branding/pxe-logo always returns a PNG now (default when no logo,
  default when SVG) so the menu always has a background.
- render_menu uses `console --picture … --top 290 || console`: paints
  the background and reserves the logo band on PNG-capable binaries
  (x86_64 UEFI), cleanly falls back to text on the others. The ASCII
  wordmark is GONE.

Only x86_64 UEFI is built from source (host-arch-agnostic cross build);
BIOS/i386/arm64 keep upstream-fetched no-PNG binaries + text fallback.
Modern clients are overwhelmingly x86_64 UEFI.

## 2. NFS AUTH_SYS credential — fixes NFS3ERR_ACCES

v0.4.68's privileged-port fix got past MNT3ERR_ACCES (mount); operators
then hit NFS3ERR_ACCES on READDIR because nfs3_client defaults to
AUTH_NONE and virtually every server exports sec=sys. We now present an
AUTH_UNIX credential (uid 0 / gid 0): no_root_squash servers treat us
as root, root_squash servers map us to anon which reads any
world-readable ISO share. Kept fixed (no UI knob) to stay dead-simple.
Hint updated: a remaining NFS3ERR_ACCES is now a server-side
permission/squash issue, not IP/auth-flavor.

## 3. FleetDM-style full-width logo (top-left)

When a custom logo is uploaded the sidebar header drops the bundled
mark + "OpenPXE" wordmark and lets the logo span the header
(left-aligned, capped 200x50, contain). Rendered server-side via a
brand-class in index_html (has_custom_logo) so there's no flash of the
default. The bundled-default case is unchanged.

Tests: 164 passing. clippy -D warnings clean. iPXE build stage
validated in isolation before the full image build.

+//! * **Logged out**. The middleware bounces `/api/*` (with the PXE
+//!   allowlist below) to `401 Unauthorized`; the front-end intercepts
+//!   that and shows `/login`.
+//!
+//! Allowlist for unauthenticated access *after* the admin is set up:
+//!
+//! * everything outside `/api/*` (the WebUI bundle, asset chrome, PXE
+//!   script endpoints, the bundled iPXE/wimboot binaries, ISO bytes,
+//!   liveness/readiness probes, the Prometheus scrape) — these are
+//!   read-only or PXE-essential and breaking them locks out booting
+//!   machines that have no way to authenticate;
+//! * `/api/setup`, `/api/login`, `/api/me` (the auth surface itself);

-//! 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.

+//! PXE boot-menu background compositor.
+//!
+//! 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:
+//!
+//!   - 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.
+//!
+//! 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.
+//!
+//! 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.

+#
+# 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
