feat: Add YouTube video support and update admin templates

- Introduced a new YouTube tech integration in `youtube.min.js` for enhanced video playback.
- Created new admin template files for managing video settings, including `index.php` and `steasyvideo-pro.tpl`.
- Updated hook templates (`device_mode.tpl`, `forquickview.tpl`, `header.tpl`, `miniature.tpl`, `miniature_tb.tpl`, and predefined templates) to include video functionality.
- Implemented caching headers in several PHP files to improve performance.
- Ensured all new templates include proper licensing information and copyright notices.
