fix: OpenRemote PUT 403/409, MQTTv5 callback, geojson-proxy API REST

- simulator.py: Fix MQTTv5 callback crash (5th arg *args)
- simulator.py: Fix _or_put() - GET version+realm before PUT, inject version in payload
- simulator.py: Fix token TTL (min 30s cache)
- simulator.py: Round-robin OR updates (~5 assets/iteration instead of 60)
- geojson-proxy: Rewrite using REST API instead of psycopg2 (PG auth issue)
- geojson-proxy: Add sensorType + attributes in properties for map styling
- docker-compose.yml: Add openremote_default network + DB vars for proxy
- docker-compose.yml: Add OR_REALM=master for geojson-proxy

Resolves: OpenRemote 403 (wrong realm in payload), 409 (missing version),
MQTTv5 callback crash, geojson-proxy DB connection failure

docker-compose.yml
