- Move stream smoothing parameters (chunk_size, delay_ms) to database config
- Remove hardcoded stream smoothing constants from StreamProcessor
- Simplify dynamic delay calculation by using config values directly
- Add invalidate_models_list_cache() function to clear /v1/models endpoint cache
- Call cache invalidation on model create, update, delete, and bulk operations
- Update admin UI to allow runtime configuration of smoothing parameters
- Improve model listing freshness when models are modified
- Handle both old and new aliases when invalidating cache during model updates
- Preserve cache info before deletion to properly invalidate after deletion
- Clear both Redis and in-memory caches on model changes
- Pass provider_model_name to invalidate_model_cache() when creating models
- Pass provider_model_aliases to invalidate_model_cache() when updating models
- Ensures alias-based resolve cache keys are properly cleared on model changes
