feat: Pulsar distribution service (Simulator → Pulsar → Brokers)

- Fix Pulsar: use binary client (port 6650) instead of non-existent REST /produce API
- Add pulsar-client to Dockerfile
- Create pulsar/distribution.py: consumes Pulsar and republishes to MQTT (EMQX/Mosquitto), NGSI-LD (Orion/Stellio), FROST
- Add docker-compose.distribution.yml for the distribution service
- Tested: Messages successfully distributed to EMQX and Orion-LD
- Update session resume
