Add GET /api/admin/health powered by a config health service that
detects common deployment mistakes: missing or read-only data volume,
broken tariffs/locale-override/guides JSON files, payment providers
enabled without credentials, webhook providers without
WEBHOOK_BASE_URL, no enabled payment methods, missing or non-https
mini app URL, missing Redis, partially configured SMTP, untrusted
reverse proxy, invalid bot token, missing/mismatched/failing Telegram
webhook and unreachable Remnawave panel. Network checks (Telegram,
panel) are cached for two minutes; ?refresh=1 forces a re-check.
The admin UI shows the alerts as a banner on the dashboard with
per-section navigation chips and a manual re-check button, and as a
filtered banner inside each affected section. Alerts are localized
via admin_health_* keys with built-in Russian fallbacks.
Keep one-off device top-ups scoped to the active subscription term and move device renewal into subscription checkout.
Carry HWID renewal metadata through provider callbacks and webhooks, including YooKassa saved-card flows.
Add admin extension controls, docs, demo data, and regression coverage.
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.
On mobile the extend input/button and the reset-trial button rendered at 36px, which felt cramped for touch. Bump them to 46px in the max-width:640px block.
