fix: resolve Telegram Mini App auth failures on all platforms

- Skip token refresh/Bearer header for auth endpoints in request interceptor
- Wait for auth store initialization before attempting Telegram login
- Clear stale session tokens when init data changes (WebView persistence)
- Show backend error details instead of generic messages
