BoulderBadgeDad b6320d1a30 Video: two system deep-scan automations (Movie + TV), independently scoped
Video twin of music's 'Auto-Deep Scan Library', split in two because Movies and TV
are separate libraries — scanning the TV library must not pull in new movies and
vice-versa.

- scanner: add a media_type param ('all'|'movie'|'show', friendly aliases) that
  gates the movies vs shows passes (and their pruning), plus an in_progress busy
  guard so the singleton scanner can't be stomped by an overlapping run.
- video_scan_library handler: thread media_type through, skip cleanly when the
  scanner is busy, and name only the scanned library in the summary.
- two system automations (owned_by=video, weekly deep scan, staggered start delays):
  'Auto-Deep Scan Movie Library' + 'Auto-Deep Scan TV Library'. Distinct action
  types (video_deep_scan_movies / _tv) because the seeder keys on action_type; both
  reuse the one handler, scoped via action_config.
- builder block gains a Library selector (Movies+TV / Movies / TV) so custom scans
  can scope too; card label/icon maps cover the video action types.

Seam tests for scanner scope + busy guard, handler scope + skip, registration set.

"""Automation handler: ``video_scan_library`` action.
The VIDEO twin of music's ``scan_library``. It does two things, in order:
1. Tells the active media server (Plex/Jellyfin) to rescan ONLY the
user's selected VIDEO sections (the movie + TV libraries chosen in
Settings) — never the music library.
2. Reads the server's current state into ``video.db`` so freshly-added
media shows up as owned on the video side.
Both run through injected seams (``server_refresh`` / ``run_video_scan``)
so the handler stays a pure function: production lazily binds the real
``core.video`` functions; tests pass fakes and never spin up Flask, a DB,
or a media-server client.
ISOLATION NOTE: this handler lives on the SHARED automation side, so it
is allowed to import ``core.video`` — the isolation contract only forbids
``core/video`` and ``api/video`` from importing the MUSIC side, not the
other way round. Video core stays import-clean; the bridge lives here.
Like ``scan_library``, the handler owns its own progress reporting
(``_manages_own_progress: True``) so the engine doesn't stomp the live
phase string with a generic 'completed' label.
