fix: handle Roo provider authentication errors gracefully

- Add RooAuthenticationError custom error class for specific error handling
- Pre-check Roo authentication before task creation to prevent UI lock-up
- Send taskCreationFailed message to unlock UI when auth fails
- Add translated error messages and button labels for all 18 locales
- Show user-friendly dialog with Sign In and Settings options
- Prevent UI from getting stuck when Roo provider is selected without authentication

This ensures users can switch providers or sign in when Roo authentication fails,
preventing the stuck state that occurred when selecting Roo without being logged in.
