The order of enabled_periods (period tariffs) and traffic_packages
(traffic tariffs) is now the storefront order everywhere — both the
Telegram keyboard and the web app. Only new tariffs-config tariffs are
affected; legacy subscription/traffic options are untouched.
- Stop sorting periods and traffic packages in the web app plans
serializer so it follows the configured order, matching the bot
keyboards that already iterate the lists as-is.
- Preserve the row order through the admin draft (load and save) instead
of sorting by months.
- Add a reusable Sortable component to the UI library (native HTML5
drag & drop with a grip handle; bits-ui/shadcn have no such primitive)
and use it to reorder period rows and traffic package rows in the
tariff editor.
Add a broadcast audience for users who registered but never had any subscription or trial (no Subscription rows at all), backed by a new get_user_ids_without_any_subscription DAL helper and a 'never' target in the webapp broadcast route.
Add GET /api/admin/broadcast/audience-counts so the audience dropdown shows the recipient count next to each option, with graceful fallback when counts are unavailable.
