Fix multiple UI and functionality issues

- Fixed together mode: Render panels before cleaning DOM so trackers display properly
- Fixed temperature unit toggle: Changed from 'celsius'/'fahrenheit' to 'C'/'F' to match config
- Fixed temperature widget: Thermometer color thresholds now use Celsius internally for consistency
- Fixed relationship remove buttons: Removed duplicate class causing wrong fields to be deleted
- Added styling for relationship remove buttons to match custom field buttons
- Added mobile font sizes for Past Events widget for better readability
- Added parsing debug log to help troubleshoot together mode issues
