Tag Aranet diagnostic entities appropriately

[aschmitz]

Proposed change

Turn the Aranet battery and interval sensors into diagnostic sensors, and enable the interval sensor by default.

Type of change

Additional information

Fixed the review comments (thanks, @Noltari!), though the commit history isn't the cleanest. I wanted to avoid a force-push and I assume you'll squash when merging, but if not let me know and I can rebase and flatten this to a single commit.

There's no need to rebase because it will be squashed when merged, so don't worry about that :)
