photos, extracted into plugins/photos — the platform half

Fifth extraction, and the clean case: no reverse dependency, configuration
already server-side, frontend already panels. Everything photos now lives at
gitea.officer.dev/plugins/photos.

Deleted, not commented: the sidecar, the api router, the db directory, the
Photos app (25 files), the screen, the App.tsx route pair, the Dashboard
barrel line, the usePageTitle rule, the AppRegistry wiring, the officerdev
barrel re-exports, the permission registry entry, both database barrels, the
hono.ts import comment, and the app-store catalogue entry.

The catalogue deletion is required rather than tidying — the trap the runbook
records as having bitten twice. permissionAvailability() derives from
sidecar_installs, which a plugin never gets a row in, so a leftover entry makes
the permission permanently 'unavailable' and withholds the route and dock tile
on a server where the plugin is installed and working.

── Test fixtures, repointed rather than deleted ──

Photos was the canonical app-store fixture across four test files, chosen for
being existing|provisioned with members: 'accounts'. Jellyfin has the identical
shape, so the assertions moved there — they are about the installer, not about
photos, and deleting them would have quietly dropped coverage of the provisioned
install path along with the plugin.

One loss worth naming: Immich's `provisioned` install mode went with the
catalogue entry. Docker provisioning for plugins does not exist yet, so photos
is point-at-your-own-instance until it does.

bunx tsgo clean. 1080 pass / 0 fail, unchanged.
