hvac: add gateway delete (retire the old Modbus gateway config)

Browse source 
There was no way to remove an mhi_gateways row either, alongside the
already-fixed device-delete gap — exposed by the same Modbus->MQTT
switchover. Adds DELETE /api/mhi-gateways/:id (manage_devices cap) and a
'Delete gateway' button. Devices referencing the gateway are NOT deleted
(mhi_gateway_id just goes NULL per the existing ON DELETE SET NULL FK) —
the confirm dialog says so and points at the separate device-delete flow
for retiring the stale mhi_modbus rows too.
