fix: resolve telegram auth token expiration and clean up codebase

- Fix stale initData comparison in clearStaleSessionIfNeeded that destroyed
  valid refresh tokens on mobile WebView reopens
- Restrict X-Telegram-Init-Data header to auth endpoints only
- Close Mini App on auth retry to force fresh initData from Telegram
- Merge Connection page error/not-configured states for better UX
- Remove unnecessary comments across 40+ files (section dividers,
  restating comments, noise catch block comments)
- Configure ESLint allowEmptyCatch to properly handle intentional
  empty catch blocks (62 warnings resolved)
