Auto capitalize first letter of entity row name

Breaking change

Proposed change

Issue was inspired by the automatic removal done by HA of area names in auto-generated dashboards. However, I can understand if my proposed fix is too far fetching.

I solved it by enforcing in general that the first letter is capitalized, since I think that looks nice and makes sense. However, if a user by design wants a lower case letter, we would prevent that then. I can only really think of this use case, if they include a brand name in their entity text where the brand starts with a lowercase letter.

If however, we only capitalize the first letter in this auto-cut-off scenario, we still would have the "brand issue'", so I would rather we are consistent for all use cases.
