feat: enhance authentication polling and refine profile UI visibility

- Update `ThemeModeOption` and `ThemeColorCard` visibility to `private` within the profile appearance section.
- Refactor `AuthenticationViewModel` to handle `PollNow` and `OnResumed` actions separately.
- Implement `forcePollNow` to trigger an immediate token check and restart the background polling job if it is no longer active.
- Add detailed debug logging to the device token polling flow to track manual requests, job status, and result states (success, pending, or failure).
