fix: re-create missing EN default template, provider type as IconGridSelect

- Template seed now re-creates missing system templates on every startup
  (not just first boot), using raw SQL to handle legacy NOT NULL columns
- Tracking configs: add provider type selector (was missing)
- All config forms: provider type uses IconGridSelect during creation,
  read-only text during editing (immutable after creation)
- Pages: tracking-configs, command-configs, command-template-configs,
  template-configs
