Improve Entity selection

[cgiesche]

The selection of entities is to be expanded with the following features:

• Beneath the name of the entity, its ID should also be displayed
• In a text field, the list of entities can be searched or filtered.

^{Originally posted by **Startrail82** February 8, 2024} Hi! I'm trying to integrate this plugin into my home management. Everything seems clear to me, but I'm bugged by the fact that I can only see entity names and not entity IDs. I have 1000+ entities in my home (don't ask...), so naturally, there are a lot of double named items. I really need to be able to set the entity ID (type it, select it, ...) and not scroll in a seemingly infinite list of entity names which are, as said, not distinguishable from each other. What's the magic trick to make this happen?
