debug: add comprehensive logging for flight mode detection

- Add detailed logs with [HIGHLIGHT-PUBLISH] prefix for publication process
- Add detailed logs with [HIGHLIGHT-UI] prefix for UI rendering
- Log relay responses, success/failure analysis, and flight mode reasoning
- Log icon decision making process in UI component
- This will help debug why airplane icon isn't showing in flight mode
