Cameron Cordes bdb69c7d37 Split main.rs: extract HTTP handlers into src/handlers/ ...

main.rs drops from 2935 → 1200 lines, freed for startup wiring +
the watcher. The 16 route handlers move into three domain-grouped
files under src/handlers/:

- handlers/favorites.rs (128 lines): favorites, put_add_favorite,
  delete_favorite.

- handlers/video.rs (665 lines): generate_video, stream_video,
  get_video_part, get_video_preview, get_preview_status. The 5
  pre-existing get_preview_status integration tests move with the
  handler (still pass against TestPreviewDao + AppState::test_state).

- handlers/image.rs (1003 lines): get_image (with the
  hash/library-scoped/bare-legacy thumb lookup), upload_image,
  get_file_metadata, set_image_gps, get_full_exif, set_image_date,
  clear_image_date. Helpers (create_circular_thumbnail,
  build_metadata_response_for_date_mutation) and request structs
  (SetGpsRequest, SetDateRequest, ClearDateRequest, UploadQuery)
  travel with them.

main.rs's import block shrinks from ~50 lines to ~22 as everything
HTTP-specific (NamedFile, mp::Multipart, BytesMut, Span, KeyValue,
StreamExt, …) moves with the handlers. The is_video_file wrapper
also goes — remaining callers in watch_files / cleanup use
file_types::is_video_file directly.

cargo test --bin image-api: 325 passing (no regression).
