feat: Centralize map tile management via Settings manager

- Add Settings.registerMap() to register maps for tile updates
- Add Settings.createTileLayer() to create tile layers from settings
- Update _updateMapTiles() to use registered maps
- Expose all maps to window object for settings manager access
- All dashboards now use Settings manager when available
- Tile provider changes in settings now apply immediately to all maps
- Use Fastly CDN for CARTO tiles (more reliable)
