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)
