v0.5.2: FleetDM login split, 3-slot branding, unattended installs

Authentication / login:
- Separate the local username/password form from the SSO "Sign in with …"
  button (FleetDM-style divider + optional IdP logo); credential fields no
  longer double as the SSO trigger. Settings → SSO copy now says SAML is live.

Branding — three slots (light / dark / client) on one row:
- Light/Dark feed the top-left mark + sign-in page by active theme (with
  cross-theme fallback; theme toggle swaps the logo live). Client feeds the
  PXE boot-menu background. Favicon pinned to the bundled mark via a new
  /assets/favicon.svg endpoint. Legacy single logo migrates to dark + client.
- BrandingStore refactored to per-slot storage; /api/branding/logo/:slot.

Unattended installs (Storage → Advanced):
- New UnattendedStore (iso-store) + /api/unattended upload/list/delete and a
  public templated serve at /unattended/:id (+ NoCloud seed dir for
  autoinstall). Accepts .ks/.cfg/.seed/.yaml/.yml/.xml/user-data; classified
  on upload; stored in its own unattended/ dir, never the ISO listing/menu.
- {{HOSTNAME}}/{{IP}}/{{MAC}} substituted per host at serve time.

Host pins + Queue profiles:
- HostBinding + QueueEntry carry an optional DeployProfile (auto_hostname /
  auto_ip / unattended_file). Hosts pin form + a per-device Queue "Profile"
  button collect them. On boot, a matched MAC has the right kernel arg
  injected (inst.ks= / preseed url= / autoinstall ds=nocloud-net) and the
  hostname/IP templated into the served answer file. DHCP stays proxy-only.

Storage:
- Remote shares default protocol is now NFS; updated descriptive copy.

235 tests green, clippy clean. Still a single static musl binary, pure Rust.

//! Operator-controlled branding overrides.
//!
//! The browser tab's logo (`/assets/logo.svg`) defaults to the bundled
//! rainbow-horizon mark. Operators who deploy OpenPXE behind their own
//! branding can upload a replacement that lives at
//! `<work_dir>/branding/logo.<ext>` and is served in preference to the
//! bundled SVG when present. Borrowed-from-FleetDM: tenant chrome, same
//! product.
//! v0.5.2 splits the single brand mark into **three independent slots**,
//! FleetDM-style:
//!
//! * `light` — shown in the WebUI top-left and on the form-login page
//! when the active theme is light.
//! * `dark` — same surfaces, when the active theme is dark.
//! * `client` — the raster painted above the iPXE boot menu entries
//! (`/branding/pxe-logo`), i.e. what a PXE client sees on the screen.
//!
//! Each slot lives at `<work_dir>/branding/logo-<slot>.<ext>` and is
//! served in preference to the bundled rainbow-horizon mark when present.
//! Borrowed-from-FleetDM: tenant chrome, same product.
//!
//! Legacy continuity: a pre-v0.5.2 single `logo.<ext>` (recorded under
//! the old `logo_filename`/`logo_mime` keys) is migrated on first load
//! into both the `dark` and `client` slots — that preserves the previous
//! behaviour (one mark fed both the dark WebUI and the PXE screen) until
//! the operator uploads dedicated variants.
//!
//! Storage policy mirrors `HostBindings` / `BootLog`: in-memory cache is
//! authoritative for the current process, disk is the source of truth on
