feat: add wifi-commissioning-service recipe

Replace wifi-commissioning-gatt-service with wifi-commissioning-service,
a complete rewrite that provides:
- Dual transport: BLE GATT + Unix Domain Socket with JSON-RPC 2.0
- Multi-socket container access for UID 10000 (omnect_device_service_client)
- Follows omnect patterns for user/group management

Changes:
- Add wifi-commissioning-service recipe infrastructure
  - Main recipe with cargo dependencies
  - Configuration .inc file with systemd unit installation
  - tmpfiles.d for runtime directory creation
  - BBClass for user/group management with pkg_postinst_ontarget

- Update bluez5 integration to reference new service name

- User/Group setup:
  - wifi_commissioning: service user and primary group
  - wifi_commissioning_client: socket access group
  - omnect_device_service_client added to wifi_commissioning_client
    at first boot to enable multi-socket container access

- Socket configuration:
  - SocketGroup changed from wpa_supplicant to wifi_commissioning_client
    to enable container access (UID 10000)
