[External integrations] Adding search and sort bar

[mutmut]

Hello @Sescandell
I just noticed that the internal integration allows sorting and searching in devices, would it be possible to have the same for the external integration in devices and discovery?
As well as the same messages for new unmanaged modules?
Thanks

Internal:

External:

EDIT: I’m adding @pierre-gilles because this seems to be related to the core.

Actually, it’s not just related to zwave-js. All external integrations are like this. So it’s a core modification.

Oh, I hadn’t noticed, I’ll change the title and category.
