fix: use docker-compose profiles to only start needed services per CI job

- Add profiles to each database service so jobs only start what they need
- Remove blanket depends_on from tests service
- Fix MySQL healthcheck to use TCP (127.0.0.1:3307) instead of Unix socket
- Fix xdebug.so warning by removing stale ini and volume mount
