PROVISORY: ci: cdrouter: OSPv2: switch USP MTP from MQTTv5 to WebSocket

Browse Source 
On the MXL25641-HDK-6 Mandatory Network Test Plan the prplos.1.2.9 test
disables Device.DHCPv4.Server. and forces the DUT to renew its WAN IPv4
lease. After the renewal obuspa's MQTTv5 TCP socket to the CDRouter
broker goes silently half-dead: the socket stays ESTABLISHED, but obuspa
sends no PINGREQ (despite KeepAliveTime=60), does not arm SO_KEEPALIVE
and does not reconnect, so every subsequent USP GET/SET times out. The
regression is 66 tests (prplos.1.2.9-1.6.23) and was confirmed on a
live bench; a manual Device.MQTT.Client.1.Enable false/true recovers
the suite instantly.

So lets workaround it by switching this one job to WebSocket MTP,
mirroring what the Candidate sibling job already does. Other platforms
are not affected and are intentionally left untouched.

Revert this block once the system-level fix for the half-dead socket
lands.
