feat: add WatchMedium field, general review editing, configurable deploy

- WatchMedium enum (cinema/streaming/tv/physical_media/download/media_server/other)
- PATCH /api/v1/reviews/:id partial update (rating, comment, watched_at, watch_medium)
- edit_review use case w/ ownership + remote review guard, best-effort AP Update broadcast
- SPA: icon picker, edit sheet (long-press mobile / pencil desktop), watch medium badge
- shared ReviewFormFields, EditableContextMenu, parse_watched_at/format_watched_at
- deploy.sh parameterized (--features, --tag), CORS allows PATCH
- CONTEXT.md glossary, ADR-0001 general review editing
