fix: Meshtastic traceroute button and dark mode maps

- Fix traceroute button in Meshtastic popups using event delegation
  instead of inline onclick handlers (more reliable with Leaflet)
- Update all maps to use dark CARTO tiles for consistency:
  - ADS-B dashboard radar map
  - AIS dashboard vessel map
  - Satellite dashboard ground map
  - APRS map
  - Satellite ground track map in main UI
- Change settings manager default tile provider to cartodb_dark
