feat: AI bug fixes, deck/collection migration, and enrichment pipeline

- Fix AI turn pipeline: add cmc to Scryfall cache, tag isRamp/isRemoval/
  isBoardWipe from oracle text during enrichment, enable post-combat spell
  casting for all difficulty levels
- Migrate deck builder, deck generator, and collection from ui/ to
  lan-client/ as iframe-embedded panels with LAB_API_BASE patching
- Fix ai-bridge.js: turnNumber, deck_name, battlefield serialization,
  5-playstyle mapping, window exports for cross-script access
- Fix engine.js: battlefieldCards flat array (not player.battlefield),
  aiDeclareAttacks extraction, combat overlay fixes
- Fix collection.js: template literal, column visibility alignment,
  set_code key, oracle text column, sortable category
- Add exile/graveyard last-card image rendering in ui.js
- Make state_encoder.py resilient to mixed input types
- Enrich type_line from Scryfall at card insert in deckbuilder.py
