Fix update status handling with cache busting and better response parsing

- Added detection of 'already have the latest version' scenario
- Implemented proper handling when no update is available with friendly message
- Added cache busting parameters to ensure fresh data from server
- Enhanced test mode toggle to properly check real update status
- Added specific handling for the case where update script runs but no update is needed
- Improved logging to show actual update check response
- Modified reload mechanics to force cache refresh with timestamp parameter
- Added special handling to avoid unnecessary page reloads
