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.

 Routes are currently in alphabetical order from PokeAPI. Update the order field in each game's JSON seed file to reflect actual game progression (e.g., Pallet Town → Route 1 → Viridian City → Route 2 → ...).
 
-## Details
-- 646 routes total across 5 games
+## Automated Approach: Bulbapedia Walkthrough Scraping
+
+We already have all location/encounter data from PokeAPI. The missing piece is progression order, which can be extracted from Bulbapedia walkthroughs.
+
+### Data Source
+Every game has a Bulbapedia walkthrough with routes listed in progression order:
+- https://bulbapedia.bulbagarden.net/wiki/Walkthrough:Pokémon_FireRed_and_LeafGreen
+- https://bulbapedia.bulbagarden.net/wiki/Walkthrough:Pokémon_Emerald
+- https://bulbapedia.bulbagarden.net/wiki/Walkthrough:Pokémon_HeartGold_and_SoulSilver
+- (and so on for all games through Gen 8)
+
+### Implementation Plan
+1. **Scrape walkthrough TOCs** - Parse the section headings from each game's walkthrough page to get route order
+2. **Normalize names** - Map Bulbapedia location names to PokeAPI location names (handle differences like "Route 1" vs "Kanto Route 1")
+3. **Generate ordering** - Create a JSON mapping of `{game: {location_name: order_number}}`
+4. **Update fetch_pokeapi.py** - Apply ordering when generating seed data
+
+### Benefits
+- Automatable for all games (Gen 1-8)
+- Bulbapedia walkthroughs are community-maintained and accurate
+- Scales as we add more games
+- Only needs to run once per game (or when walkthroughs update)
+
+### Considerations
+- Gen 9 (Scarlet/Violet) is open-world so ordering is less meaningful
+- Some games have branching paths - may need to pick a canonical order
+- Name matching between Bulbapedia and PokeAPI may need fuzzy matching
+
+## Current Scope
 - FireRed and LeafGreen share the same route progression (Kanto)
 - HeartGold and SoulSilver share the same route progression (Johto + Kanto)
 - Emerald has its own progression (Hoenn)
-- So effectively 3 unique orderings to define
-- After updating JSON files, re-run the seed: `podman compose exec -e PYTHONUNBUFFERED=1 -w /app/src api python -m app.seeds`
+- So effectively 3 unique orderings to define for current games
