Add all Gen 1-9 games with colors to seed data

- Add 37 games from Gen 1-9 (Red/Blue through Scarlet/Violet)
- Add color field to Game model matching box art/branding
- Add migration for games.color column
- Update fetch_pokeapi.py to fetch all games and output colors
- Update seed loader to upsert game colors
- Update frontend Game type to include color field

Games without PokeAPI encounter data (ORAS, Let's Go, Sword/Shield,
BDSP, Legends Arceus, Scarlet/Violet) have location structure but
empty encounter tables.
