refactor: improve media service client methods and clean up test files

- Introduced helper methods `getMediaEndpoint` and `getMediaSoapClient` in the media client for better code reuse and clarity.
- Updated various media service methods to utilize the new helper methods, enhancing maintainability.
- Cleaned up test files by standardizing formatting and removing unnecessary blank lines for improved readability.
