feat(cache): improve model cache invalidation for alias resolution

- Add provider_model_name and provider_model_aliases to invalidate_model_cache()
- Clear resolve cache keys for both model name and aliases when invalidating
- Also clear resolve cache in invalidate_global_model_cache() for GlobalModel names
- Handle SQLite gracefully by catching OperationalError and ProgrammingError
- Optimize fallback query to pre-filter by provider_model_name when JSONB fails
