feat: add useApiSettings hook for managing API settings, including providers, endpoints, cache, and model pools

- Implemented hooks for CRUD operations on providers and endpoints.
- Added cache management hooks for cache stats and settings.
- Introduced model pool management hooks for high availability and load balancing.
- Created localization files for English and Chinese translations of API settings.
