Add HLS.js support and enhance content streaming logic

- Integrated HLS.js version 1.6.15 into the project for improved video streaming capabilities.
- Updated the ContentsController to check for HLS manifest availability and fall back to presigned URLs for original files if not found.
- Enhanced the VideoPlayer component to handle loading and error states more effectively, improving user experience during streaming.
- Refactored content service methods to return detailed streaming information, including HLS and DASH manifest URLs.
