fix(api): add docker_cleanup parameter to stop endpoints

Add optional docker_cleanup query parameter to the stop endpoints for
Services, Applications, and Databases. This allows API users to control
whether docker cleanup (pruning networks, volumes, etc.) is performed
when stopping resources.

The parameter defaults to true for backward compatibility.

API Usage:
- Stop without docker cleanup: GET /api/v1/{resource}/{uuid}/stop?docker_cleanup=false
- Stop with docker cleanup (default): GET /api/v1/{resource}/{uuid}/stop

Fixes #7758
