feat(kuma-cp): add support for inspect api for new kind Dataplane and section name for selecting single inbound

[Automaat]

Fix: #12361

Motivation

We have introduced new kind and we need inspect api support for this, as it turns out it works out of the box so I've just added test for it.

This needs #12573 to be merged first
