Admin can now attach photos, videos, and documents when replying to
tickets. Upload happens on file selection via existing media upload
endpoint. Includes attachment preview with type-specific icons,
upload progress, error handling, race condition protection, and
proper blob URL lifecycle management.
Added video player rendering for video attachments in message thread.
Updated ticket list preview to show [media_type] for media-only messages.
Fixed issue where users had to click the Telegram Mini App back button twice
in many admin pages. The replace flag was causing conflicts between Telegram's
BackButton internal history and React Router's history management.
Updated all 32 admin pages to use simple navigate() calls without replace flag.
Add replace: true to all navigate() calls in useBackButton hooks
Prevents history cycles when navigating back and forth
All 32 admin pages now use navigate(path, { replace: true })
Back button now goes directly to parent without cycling
Main sections navigate to /admin (15 pages)
Detail/edit pages navigate to parent lists (16 pages)
All pages use useBackButton hook with proper navigation paths
Native Telegram back button in Mini App, UI button on web
Email template pages keep UI-only back buttons as required
Major changes:

- Add email channel support for broadcasts
- Remove pull-to-refresh, improve drag-and-drop on touch devices
- Fix Telegram Mini App: fullscreen, back button, scroll restoration
