- Fix: flashcard task used wrong Redis key prefix (job: vs extraction:)
causing progress to stay on "pending" after completion
- Flashcards are now user-scoped: each user sees only their own decks
- Soft-delete decks: DELETE moves to trash, ?permanent=true to destroy
- Trash tab on flashcards page: restore or permanently delete decks
- Delete individual cards with inline confirmation in browse view
- Card edit/delete now allowed for deck owner (not just moderators)
- ExtractionProgress label prop: shows "Generating Flashcards" not
"Extracting Questions" for flashcard jobs
- Added deleted_at column to flashcard_decks
