Merge branch 'swiftyos/caching-pt2' into swiftyos/shared-cache

Addresses all 14 review comments from @majdyz on PR #11030

Major architectural improvements:
- Move cache.py from autogpt_libs to backend/util for proper dependency management
- Add Redis configuration to Settings class for centralized config management
- Remove duplicate retry.py from autogpt_libs (use backend.util.retry)
- Implement dedicated Redis connection pool with 50 max connections

Cache API enhancements:
- Make ttl_seconds a required parameter (no infinite TTLs allowed)
- Add CachedValue dataclass to eliminate tuple ambiguity when caching tuple results
- Implement LRU with TTL refresh using Redis GETEX command
- Add pattern-based cache clearing: cache_clear(pattern="user:*")
- Simplify wrapper logic by extracting helper functions

Redis integration:
- Create separate connection pool for cache (binary mode for pickle)
- Add recommended Redis production configuration in comments
- Use Settings class for Redis config instead of environment variables directly
- Update both cache.py and redis_client.py to use centralized settings

Test improvements:
- Move test file from autogpt_libs to backend/test
- Fix tests to use pickleable data structures instead of MagicMock objects
- Update all @cached() decorators to include ttl_seconds parameter
- All 51 cache tests passing

Breaking changes:
- @cached() decorator now requires ttl_seconds parameter
- Import path changed: autogpt_libs.utils.cache -> backend.util.cache
- Tests using shared_cache=True must return pickleable objects
