refactor: update HTTP request handling and improve documentation

- Replaced http.NewRequest with http.NewRequestWithContext in client tests for better context management.
- Updated method names and comments for clarity, including renaming GetWsdlUrl to GetWsdlURL and StorageUri to StorageURI for consistency.
- Enhanced comments across various files to provide clearer descriptions of functionality and ONVIF specifications.
