fix: e2e failures on the device: edit replies before their events, /ws closed on reboot

- runModelEdit sent an edit's events (room, roomRemoved, the orders,
  repeaters) before its reply, where PROTOCOL.md says they follow it. A
  client waiting for the reply read past them (test_adding_and_deleting_a_room).
- A restart dropped the /ws connections without a close, so clients never
  saw them go (test_reboot). ESPNetwork::end() now closes them too.
