refactor: remove unused OPENAI_API_KEY and GOOGLE_API_KEY

Removed all references to OPENAI_API_KEY and GOOGLE_API_KEY since only
Claude (Anthropic) provider is implemented. These were placeholder references
for future providers that don't exist yet.

Changes:
- Removed OPENAI_API_KEY and GOOGLE_API_KEY from docker-compose.yml
- Removed from .env and .env.example files
- Updated setup/routes/store-api-key.ts to only support anthropic
- Updated setup/routes/delete-api-key.ts to only support anthropic
- Updated setup/routes/api-keys.ts to only return anthropic key status
- Updated models/routes/providers.ts to only list anthropic provider
- Updated auto-mode-service.ts error message to only reference ANTHROPIC_API_KEY

Backend test results: 653/653 passing ✅
