Add game category and region metadata for genlocke presets

Add `category` field (original/remake/enhanced/sequel/spinoff) to the
Game model and tag all 38 games. Create regions.json with generation
mapping, ordering, and genlocke preset defaults per region. Add
GET /games/by-region endpoint returning games grouped by region.

 - However, a dedicated generations reference would be useful for UI purposes (showing all generations even if not all games are seeded yet)

+## Decisions
+- Legends games (Hisui, Lumiose) are excluded from genlocke presets — available via Custom only
+- Black 2/White 2 are grouped with Black/White in the same Unova slot (category: sequel)
