Show rooms/labels/… in the drop down chooser

[ctron]

When setting up a new visualization, the UI allows one to select devices/entities through a dropdown, which can also search. However, that sometimes can get tricky if all those devices are named in a similar pattern:

All those devices are actually assigned to rooms, but this information is not visible in the drop down. Given the new labels system, it would also be cool to see those labels too.

Maybe it would be possible to show some additional badges/shields/labels like in this example (different topic, but still a similar case):

Adding the room itself should be simple, as (to my understanding) there can only be one. For labels it might be a bit more complicated.

I think having this feature would make it a lot easier choosing the right entity. And yes, one could just rename those entities. However, in some cases that's not possible, because those names are imported from external systems/integrations. And also that would mean re-creating those devices if one would want to relocate them to a different room.
