Initial commit of TESmart kvm (#3262)

* Initial commit of TESmart kvm

did my best to crop marketing images

* Update device-types/TESmart/HKS801-P23-USBK.yaml

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* nit / typo fix

`precedent` is what I meant...

* lint `"` -> `'`

_sigh_

* better classify the LAN port as an interface

with the `mgmt_only` flag set.

* oops, forgot th dangling `x`

Properly classify the type of LAN interface
