add photos, an immich-backed library behind its own sidecar

officer-photos owns the whole Immich contract: the instance URL and the API
key live there and nowhere else, and the platform side is an auth-gated
forwarder holding no credentials. The route surface is an allow-list keyed on
the first path segment, so admin, auth, api-keys, sessions, jobs, system-config
and libraries are unreachable by construction rather than by enumeration.

The UI mirrors Immich's own sidebar — timeline, explore, map, search, albums,
people, favorites, sharing, archive, trash — because the point of a sidecar
screen is to reproduce what the upstream already ships, then extend it. The
timeline reads Immich's columnar time-bucket format directly; selection lives
in the URL per docs/navigation-audit.md.

Two things worth knowing for anyone touching this later:

- `duration` is an integer count of milliseconds in Immich 3.0. It was an
  HH:MM:SS.mmm string before, and every stale example still shows that form.
- the map container is sized with h-full/w-full, never `absolute inset-0`.
  maplibre's stylesheet sets `position: relative; overflow: hidden` on the
  element it is given, and an unlayered vendor rule beats Tailwind 4's layered
  `.absolute` regardless of source order — so the div collapses to height 0 and
  clips its own canvas away. Nothing errors: the GL context is healthy, tiles
  download and pixels are drawn into a buffer nobody ever composites.

maplibre-gl is pinned to 5.x deliberately; 6.0 resolves a separate worker file
from import.meta.url, which Officer's index.html fallback answers with HTML.
