tiles.wmflabs.org was causing DNS resolution failures on the device/emulator
(No address associated with hostname, errno = 7). Replaced with the official
OpenStreetMap tile server (tile.openstreetmap.org) which is more stable and reliable.
Removed subdomains configuration as it's not needed for the official OSM server.
- Updated FireMapLayer.osmcGrey in genericMap.dart
- Updated TileLayer in monitoredAreas.dart
- Fixes: Map tiles not loading due to network/DNS issues
Maps were not rendering in flutter_map v6.2.1 because TileLayer was missing the
required userAgentPackageName property. This property is needed for proper
HTTP requests to tile servers with correct User-Agent headers.
- Updated TileLayer in genericMap.dart with userAgentPackageName
- Updated TileLayer in monitoredAreas.dart with userAgentPackageName
- Fixes: Maps not displaying tiles after flutter_map v6 migration
