Update CacheManager.get() and CacheManager.set() type annotations to
accept Any JSON-serializable type (dict, list, str, int, bool, None)
instead of just dict.
This fixes type checker warnings in base_service.py where lists are
cached for API responses. The runtime behavior was already correct,
this just aligns the type hints with actual usage.
Changes:
- CacheManager.get() return type: Optional[dict] -> Optional[Any]
- CacheManager.set() data param: dict -> Any
- Updated docstrings to clarify JSON-serializable types
