Subject: [PATCH] Fix: Use CartoDB Positron for osmcGrey layer (reliable b/n
 tiles)

CartoDB Positron (light_all) is a modern, reliable replacement for the
deprecated Stamen Toner and tiles.wmflabs.org. It provides a clean
grayscale/minimalist map style with excellent availability.

- Updated FireMapLayer.osmcGrey to use CartoDB Positron
- Updated monitoredAreas TileLayer to use CartoDB Positron
- Keeps subdomains configuration for load distribution
- Fixes: Unreliable tile server DNS issues
