fix(rest-api): Populate RoutingProfileType directly from the controller value

[bcavnvidia]

Description

we don't sync tenant routing profile details from core to rest. Core expects full updates for objects (i.e., it expects all fields) and empty fields signal a "clear". If a tenant change in the REST API triggers an update from the inventory processes, rest-api is sending tenant updates and not setting the profile field because it's not aware of it. From core's pov, it's an attempt to change/clear the profile type, and it will be rejected if the tenant has VPCs.

This PR updates the inventory process to echo back the tenant routing profile until this becomes a new tenant model field in the REST API and is fully synced.

Thanks @bcavnvidia. We could also pass it as an argument to tenant.ToUpdateRequestProto()
