Add parts of previous pull requests, add local unique IDs and fix latest deprecation warnings

[jaym25]

A full cleaning and update of the Remote Home-Assistant component.

Except for the version bump, happy to merge that, and could make a new release afterwards

You can let me know then if I should still add you to the repo :)

[jaym25]

Go ahead and add me. I would be honored.

[jaym25]

You might have to help me a little with the process, as I'm green when it comes to this stuff...

[jaym25]

If you use this component, you'll love the unique IDs where you can easily rename and assign the entities to areas plus everything else. Been having that for several months now and love it! I'm also using it bidirectionally.

[lukas-hetzenecker]

Thanks, I have added you :) - feel free to merge the PR ;)

[jaym25]

That felt good! It didn't pass the manifest alphabetical requirement test, but I just did it anyway. Hope that's not a problem :-)

@lukas-hetzenecker what are the red and green gauges on each file in a pull request supposed to tell you?

[jaym25]

@lukas-hetzenecker do we have to anything else to make it show up in HACS?

[lukas-hetzenecker]

Congratulations on the first merge @jaym25 🥳🥳🥳
The tests are indeed not that important, we can fix that later

For making it show up in HACS - yes, there's some additional step
Under the release tab ( https://github.com/custom-components/remote_homeassistant/releases ) we have to "Draft a new release". For the tag, a new tag with the same version number as in the manifest file can be created.
Then some (potentially autogenerated) release notes, and it will show up in HACS. Do you want to have the honor? :)

[lukas-hetzenecker]

Oh, and the red/green gauges in the Files just show the amount of the lines of code that have been removed/added

[jaym25]

I fixed manifest to version 4.0 and alphabetical... Created the new tag and published!! Thank You!!
