Adds a comprehensive host blocking system that prevents requests to specific disallowed hosts across all online streaming services. The implementation includes:
- New `NotAllowedHosts` HashSet containing base64-encoded blocked hostnames
- `IsNotAllowedHost()` method to validate URLs before making HTTP requests
- Integration in all service classes (Anihub, AnimeON, Bamboo, CikavaIdeya, StarLight, UAKino, UaTUT, Uaflix, Unimay)
- Checks applied to search, content fetching, and streaming URL resolution
- Consistent implementation pattern across both Invoke and Controller classes
This security enhancement prevents connections to potentially malicious or unauthorized streaming hosts while maintaining existing functionality for allowed sources.
