Emergency Module Audit

The emergency_maps_service.py is responsible for locating nearby emergency services.

Key Findings:

1. Fallback Logic: It supports Google Maps but seamlessly falls back to local OpenStreetMap (OSM) via Overpass API queries (fetch_emergency_nearby_sync).
2. Categories Supported: Hospital, Fire Station, Police, Ambulance, Emergency Supplies.
3. Simulated Traffic/ETA: Uses Haversine distance and simulates driving metrics (assumes 25% longer route, 40km/h average speed, and +18% delay for moderate traffic).
4. Resilience: Has mirrors for Overpass API (overpass-api.de and overpass.kumi.systems).

Recommendations:

• Add caching for the fetch_emergency_nearby_sync to reduce external API hits.
• Make the traffic delay multiplier configurable.
