Add OpenPanel self-hosted analytics template

This PR introduces a new template for self-hosting OpenPanel, an open-source analytics platform for web and mobile apps.

This is just something quick I made to test it out. It works when you spin it up, but maybe not the best practices for the template so would love some feedback to bring it to coolify.

The only issue is, i don't think replicas are allowed since the amount of workers is replicated to how many cores you choose to use.

    image: lindesvard/openpanel-worker:latest
    restart: always
    depends_on:
      - op-db
      - op-ch
      - op-kv
    deploy:
      mode: replicated
      replicas: 12

FYI, Carl added migrations for DB structure of ClickHouse, so you'd better not embed it into the template.

2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
