+Tests for BATON-005: Admin panel — user creation, password change, block/unblock, delete.
+
+Acceptance criteria:
+1. Создание пользователя — пользователь появляется в БД (GET /admin/users)
+2. Смена пароля — endpoint возвращает ok, 404 для несуществующего пользователя
+3. Блокировка — заблокированный пользователь не может отправить сигнал (403)
+4. Разблокировка — восстанавливает доступ (сигнал снова проходит)
+5. Удаление — пользователь исчезает из GET /admin/users, возвращается 204
+6. Защита: неавторизованный запрос к /admin/* возвращает 401
+7. Отсутствие регрессии с основным функционалом

+Tests for BATON-006: не работает фронт — {"detail":"Not Found"}
+
+Acceptance criteria:
+1. nginx/baton.conf содержит location /api/ (prefix match), проксирует на FastAPI.
+2. nginx/baton.conf содержит location /health, проксирует на FastAPI.
+3. nginx/baton.conf содержит location / с root и try_files (SPA-поведение).
+4. GET / на FastAPI возвращает 404 (маршрут /  не зарегистрирован в main.py —
+   статику должен отдавать nginx, а не FastAPI).
+5. GET /health возвращает 200 (FastAPI-маршрут работает).
+6. POST /api/register возвращает 200 (FastAPI-маршрут не сломан).
+7. POST /api/signal возвращает 200 (FastAPI-маршрут не сломан).
+8. POST /api/webhook/telegram возвращает 200 с корректным секретом.
