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
