Implement complete MyBeacon backend MVP

Backend Features:
- JWT authentication (access + refresh tokens)
- Multi-tenant architecture with organization isolation
- RBAC with 6 roles: superadmin, owner, admin, manager, operator, viewer
- Automatic device registration with toggle switch
- Stub-compatible Device API (POST /registration, GET /config, POST /ble, POST /wifi)

API Endpoints:
- /api/v1/auth/* - User authentication (login, register, refresh, me)
- /api/v1/superadmin/* - Superadmin management (organizations, users, devices, settings)
- /api/v1/client/* - Organization management (users, devices, organization info)
- /api/v1/registration - Device auto-registration
- /api/v1/config - Device configuration retrieval
- /api/v1/ble - BLE events batch upload
- /api/v1/wifi - WiFi probe events batch upload

Database:
- PostgreSQL 16 with async SQLAlchemy
- Device simple_id auto-increment (Receiver #1, #2, #3...)
- Settings table for auto-registration toggle
- Devices table with token/password credentials
- Multi-tenant isolation via organization_id

Security:
- JWT tokens with type field (access, refresh, device)
- Device authentication via MAC address → token
- Bcrypt password hashing
- Auto-registration with 1-hour auto-disable after last device

Tested:
- Device auto-registration working on real hardware (192.168.5.244)
- BLE events receiving and logging
- Multi-tenant isolation verified
- RBAC permissions working

+## Запуск сервера
+
+```bash
+cd /home/user/work/luckfox/alpine/mybeacon-backend/backend
+poetry run uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+Сервер доступен по адресу: `http://192.168.5.4:8000`
+
+API документация (Swagger): `http://192.168.5.4:8000/docs`
+
+## Тестирование на реальном железе
+
+### Подготовка
+
+1. **Зарегистрировать устройство** через superadmin API:
+   ```bash
+   curl -X POST http://192.168.5.4:8000/api/v1/superadmin/devices \
+     -H "Authorization: Bearer YOUR_SUPERADMIN_TOKEN" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "mac_address": "REAL_DEVICE_MAC",
+       "organization_id": 4
+     }'
+   ```
+
+2. **Обновить MAC-адрес** в демо-скрипте:
+   ```bash
+   nano /tmp/demo_hardware.sh
+   # Изменить DEVICE_MAC на реальный MAC устройства
+   ```
+
+3. **Запустить демо** на железке (192.168.5.244):
+   ```bash
+   # Скопировать скрипт на железку
+   scp /tmp/demo_hardware.sh root@192.168.5.244:/tmp/
+
+   # Запустить на железке
+   ssh root@192.168.5.244 'bash /tmp/demo_hardware.sh'
+   ```
+
+### Проверка работы демона
+
+Демон настроен в `/home/user/work/luckfox/alpine/overlay/etc/init.d/S98mybeacon`:
+- Сервер: `http://192.168.5.4:8000` ✅ (обновлен)
+- Heartbeat: каждые 60 секунд
+- События: WiFi probes и BLE scans
+
+Запуск демона на железке:
+```bash
+ssh root@192.168.5.244 '/etc/init.d/S98mybeacon start'
+```
+
+Проверка логов:
+```bash
+ssh root@192.168.5.244 'tail -f /var/log/mybeacon.log'
+```
+
+## Тестовые скрипты
+
+### 1. Полное тестирование Client API
+```bash
+bash /tmp/test_client.sh
+```
+
+### 2. Полное тестирование Device API
+```bash
+bash /tmp/test_device_api.sh
+```
+
+### 3. Демонстрация интеграции с железом
+```bash
+bash /tmp/demo_hardware.sh
+```
+
+## Результаты тестирования
+
+### ✅ Authentication
+- Register: работает
+- Login: работает (access + refresh tokens)
+- /me: работает
+- Refresh token: работает
+
+### ✅ Superadmin API
+- Organizations CRUD: все endpoints работают
+- Users CRUD: все endpoints работают
+- Devices CRUD: все endpoints работают
+- RBAC: обычные пользователи получают 403
+
+### ✅ Client API
+- Organization info: работает
+- User management: работает
+- Device viewing: работает
+- Multi-tenant isolation: работает (403 при попытке доступа к другой организации)
+
+### ✅ Device API
+- Authentication: работает (JWT токен с type="device")
+- Get config: работает
+- Heartbeat: обновляет last_seen_at и metadata
+- Events: принимает WiFi/BLE события
+- Metadata в config: uptime, load_avg, memory_free, cpu_temp
+
+## Следующие шаги (Post-MVP)
+
+### 1. Audit Logging (Приоритет 1)
+- Middleware для автоматического логирования всех действий
+- Endpoints для просмотра audit logs
+
+### 2. ClickHouse Integration (Приоритет 2)
+- Хранение WiFi/BLE событий в ClickHouse
+- Аналитика по событиям
+- Графики и статистика
+
+### 3. WebSocket для BLE Map (Приоритет 3)
+- Real-time обновления позиций BLE-устройств
+- WebSocket endpoints
+- Frontend карта с локациями
+
+### 4. Frontend (Приоритет 4)
+- Vue 3 + Vite
+- Login/Register страницы
+- Dashboard для superadmin
+- Dashboard для client (organization view)
+- Device management UI
+
+### 5. Production Deployment
+- systemd service для backend
+- nginx reverse proxy
+- SSL certificates
+- Environment-specific configs
+
+## Технологический стек
+
+- **Backend**: Python 3.11, FastAPI, SQLAlchemy (async)
+- **Database**: PostgreSQL 16
+- **Cache**: Redis (готов к использованию)
+- **Authentication**: JWT (python-jose)
+- **Password hashing**: bcrypt
+- **Migrations**: Alembic
+- **Development**: Poetry, uvicorn --reload
+
+## API Security
+
+- JWT tokens с expiration
+- Device tokens с type="device"
+- RBAC на уровне endpoints
+- Multi-tenant isolation в queries
+- Password hashing с bcrypt
+- HTTPS ready (nginx будет терминировать SSL)
+
+## Known Issues & Improvements
+
+**Исправлено:**
+- ✅ JWT "Subject must be a string" - исправлено (конвертация в string)
+- ✅ Device simple_id NULL - исправлено (server_default)
+- ✅ Bcrypt/passlib compatibility - исправлено (прямой bcrypt)
+- ✅ Device token type verification - исправлено (type="device" support)
+
+**TODO:**
+- [ ] Email verification (сейчас заглушка)
+- [ ] Password reset flow
+- [ ] Rate limiting на login endpoint
+- [ ] Audit logging middleware
+- [ ] WebSocket для real-time updates
+- [ ] ClickHouse для event storage
