feat: add audit logging for admin trash restore/purge and notification clear actions

- Record audit events in `admin_trash_restore` and `admin_trash_purge` endpoints with target metadata
- Log `notification.read.all` event when user clears devRant notification feed
- Include `devrant` as a valid origin in audit categories
- Add `admin_section` and `pagination_query` fields to audit and backup schemas for UI consistency
