Docker tab: own config file, folder.view3 becomes optional sync target

- Primary store moved to /boot/config/plugins/varaverk/docker_folders.json
- No dependency on folder.view3 plugin being installed
- Auto-imports folder.view3 JSON on first run if it exists (one-time bootstrap)
- Mirrors writes to folder.view3 JSON only if that plugin's directory is present
- Toolbar shows '⇄ folder.view3' badge when sync is active
