Fix Grafana port mapping in docker-compose.yml

[Copilot]

Grafana listens on port 3000 by default, but the docker-compose configuration was mapping 3030:3030, making the service inaccessible.

Changes

• docker-compose.yml: Updated grafana-server port mapping from 3030:3030 to 3030:3000
• README.md: Updated Grafana URL from http://localhost:3000 to http://localhost:3030

# Before
grafana-server:
  ports:
    - 3030:3030

# After  
grafana-server:
  ports:
    - 3030:3000

Grafana is now accessible at http://localhost:3030 when running via docker-compose.

<issue_description>Hi!,

There is a small problem on docker-compose.yml. grafana-service maps ports 3030 to 3030, but the the server is listening on port 3000. So, it should be:

ports:
    - 3030:3000

@copilot I'll prefer you keep the grafana default port 3030:3000
