• ensure settings only show when Any merge request is selected
• add tooltips where needed

Verification steps

1. Upload a GitLab Ultimate license
2. Navigate to a project/group => Secure => Policies => New policy => Scan result policy
3. Verify setting updates appropriately and changes if changed in yaml mode
