implement Edge-Hub integration with user_id validation (SCRUM-93, SCRUM-94)

- Agent: Updated config and main
- Edge: Implemented adapter factory in main.py to switch between MQTT and HTTP.
- Edge: Updated AgentData entity and processing logic to support user_id.
- Infrastructure: Configured docker-compose for dynamic protocol switching and environment management.
