feat(catalog): Scryfall bulk data import + Tagger community tags
Add full Scryfall bulk data pipeline:
- Migration: 13 new columns on `cards` (oracle_id, illustration_id,
color_identity, keywords, legalities, flavor_text, artist, released_at,
layout, edhrec_rank, reserved, reprint, finishes) with GIN indexes
for JSONB search.
- Migration: `tags` + `card_tags` tables for Tagger community data.
- Script: `bulk-import-scryfall.js` — downloads Oracle Cards bulk file
(168 MB) and upserts all 36k+ MTG cards with rich metadata.
- Script: `import-scryfall-tags.js` — imports oracle tags (4.5k tags,
227k taggings) and art tags (11k tags, 458k taggings).
- Lib: `bulk-sync.js` — runtime bulk sync callable from the admin API.
- Admin UI: mode toggle (incremental vs bulk) on catalog sync panel.
Enables Commander deck validation (color_identity), format legality
checks, keyword search, EDHREC popularity ranking, and functional
card tagging ("removal", "ramp", "draw") for deck building assistance.
