Labels: add filtering by "no labels" (similarly - for "area" & "blueprint")

[ildar170975]

Currently it is possible to filter a table by some label (labels):

Suggest to add one more criteria - "no labels" (or with a similar meaning):

If this criteria is selected - a table will contain elements w/o labels associated.
This criteria cannot be selected together with other label: if "no labels" is selected - then other label-based criteria are ignored.

Similarly:

• for "Areas" - to allow select entities which are not associated to any area;
• for "Blueprint" - to allow select automations/scripts which are not based on any blueprints.

Yes, should be a great thing to add a "no label" AND a "no category" filter.
But you have to be able to check it together with other label /category. This way you could display i.e. every automation, except the ones wich labels are not selected.

Yes! Same with every list that can be filtered. As someone would like to identify items in a filtered list that are missing whatever the filter needs, I would like to be able to filter for items that can't be filtered.

This feature would be highly beneficial for identifying and organizing unclassified entities more efficiently.

Use Case
Allows users to quickly find entities that have not been assigned labels.
Particularly useful for discovering new entities, especially in large Home Assistant setups.

Implementation Suggestion
Extend the existing label filter logic by introducing a 'No Label' option.
Initially, I considered that selecting this option should automatically deselect all other label filters to ensure that only unlabeled entities are displayed. However, an even more flexible approach would be to allow label filters to be combined. For example, enabling users to filter for both unlabeled entities and entities with a specific label, such as "Show all entities without a label AND all entities with label XYZ."
