fix(phase3): fix database/device access in search, backup, stats, map endpoints

- Search, backup, stats endpoints used current_app.config.get('DEVICE_MANAGER')
  which doesn't exist — replaced with _get_dm()/_get_db() helpers
- /api/device/info used old v1 CLI — replaced with DeviceManager.get_device_info()
  returning structured dict instead of string (fixes map own device marker)
- Moved search button from navbar to FAB menu (between filter and DM buttons)
- Bump SW cache to v7
