fix: preserve isLocalOnly and publishedRelays in eventToHighlight

- Attach custom properties to event as __highlightProps before storing
- Update eventToHighlight to preserve these properties when converting
- This ensures highlights loaded from EventStore maintain flight mode status
- Fixes issue where isLocalOnly was undefined in UI component
- The airplane icon should now show correctly for flight mode highlights
