feat: restore monitoring widget + add sami-files template

- Recreate status/js/monitoring-widgets.js with robust services count
  (reads from window.APPS, #cards DOM, then live fetch as fallback)
- Add sami-files service to data/services.json (Sami Files card)
- Add sami-files template to app-templates.js under 'Files' category
  with full systemd deployment docs and Caddy snippet
- Bundle monitoring-widgets.js into init.js
