Free CDN control system added for remote management of multiple CDN servers

This update improves the included free CDN system with caching for more file extensions. By default, it now caches m3u8, ts, key, jpeg, png, jpg, webp and other supported files. The CDN controller is also integrated into the EFV administration interface. You can install the CDN system on multiple servers, monitor resources and manage commands directly from EFV. It automatically checks the CDN system's status and issues recovery commands when abnormalities occur, attempting to restore normal operation.

Changelog

1. Integrated the cdn system into the EFV administration interface. Install the CDN system on multiple servers and issue commands remotely, including binding domains and automatically requesting SSL certificates. The controller also checks the CDN system's status and issues recovery commands when abnormalities occur, attempting to restore normal operation.
2. The cdn system now caches more file extensions, including m3u8, ts, key, jpeg, png, jpg and webp.
3. Added search and improved redownloading in the download center. If a downloaded video has been deleted in video management, you can add all matching videos back to the download queue in one action.
4. Restored static PNG segment generation. Choose generated PNG segments or segments disguised as JPEG according to your needs.
5. Improved the APIs for importing and updating series and video details, with more parameters. See the documentation for details.
6. Improved on-demand ass watermark replacement. After each replacement, changed TS segments are resynchronized to the corresponding cloud storage.
7. Multi-user ftp uploads now support importing series covers. Both series and videos support importing details such as tags and descriptions.
