feat: project-scoped Docker image prune, conflict fix, deploy toggle, access list picker

- Image prune only removes images matching project image refs, skips active instances
- Add ListImagesByRef and RemoveImage to Docker client
- Fix 409 conflict: use listProjects instead of duplicate POST
- Add "Deploy immediately" toggle to Quick Deploy (off by default)
- Replace raw access list ID with EntityPicker on project edit form
- Trigger proxy resync on access list change
- Fix stage form layout: single responsive row
- Fix empty port default on project creation
- Improve inspect error message for remote Docker
