Add webinar recording page with embedded video player

Changes:
- Create WebinarRecording page with embedded video player
- Supports YouTube, Vimeo, Google Drive, and direct MP4
- Check access via user_access or paid orders
- Update webinar recording buttons to navigate to page instead of new tab
- Add route /webinar/:slug

This keeps users on the platform for better UX instead of
redirecting to external video sites.
