[FEAT] Add Services as available assignments

Feature description:

Because we now have a lot of services to plan (Audio, Zoom, Cleaning, Microphones, and so on), It would be great if this was possible too. We are just investigating an alternative to New World Schedular and this feature would make the switching point for us.
Thanks for your work!

Servus @4IngoJ 👋

Thanks for your post. Recently, we're getting indeed a lot of requests regarding the meeting duties and cleaning scheduling.

It's our goal is already for a long time. And now, after we added most of the other core features, we're already working on the meeting duties and the hall cleaning is in the development queue.

Thanks for your support! If you're a developer and would like to help speed up the development of new features, your contribution is always welcome! 🚀
