feat: drag-and-drop dashboard editing, alert dynamic fields

Browse Source 
- Replace up/down arrow reorder buttons on dashboard edit page with
  SortableJS drag handles; add POST /d/<id>/edit/reorder endpoint
  accepting ordered widget ID array
- Add {% block extra_scripts %} hook to base.html for page-specific JS
- Add dynamic alert rule field loading via HTMX partial (_rule_fields)
  so metric/threshold fields update when source is changed
- Add docs/plugins/index.yaml.example showing catalog index format
