Grabs now carry the movie's identity so the Downloads cards are rich, not anonymous:
- video_downloads gains media_id / media_source / year / poster_url (schema v15 +
migration); grab stores them (passed from the get-modal → download view → grab).
- Cards show the POSTER in the art tile (emoji fallback), 'Title (Year)', a quality
chip (1080p · BluRay · X265), and an ↗ Open button that jumps to the movie/show
detail page (dispatches soulsync:video-open-detail). Cancel/retry unchanged.
16 tests green, ruff + balance clean.
