fix: update rapidyaml requirement for Python 3.12 compatibility and add missing import

[LaSi5002]

rapidyaml==0.8.0 is incompatible with Python 3.12. Caused error on pip install -e .
from fourc_webviewer.fourc_webserver import FourCWebServer was removed 2 days ago. Probably accidentally.

Thank you for this fix! We try to establish some first actual tests of the webviewer soonish, such that these things should not occur anymore.

Hey @LaSi5002, thanks for the fixes. Regarding the requirements, your fix is absolutely correct. However, I don't get this error message 🤔 Which operating system are you using?

[LaSi5002]

Hi @gilrrei im on Windows 11. But it seems weird that it worked before on your systems. Are you sure that you ran it with the 3.12 interpreter?

[c-p-schmidt]

Yes, we use python 3.12 on an Ubuntu 24.04 operating system.

4C and most of the subprojects are only fully tested and supported on Ubuntu 24.04. There is a strong dependency of the OS on Python packages. This is exactly what you observed; in this instance, it has nothing to do with the Python version.

The fix you provided is only required for Windows and macOS. Once fourcipp (which is the dependency that requires rapidyaml) is updated, this fix is no longer required.

@c-p-schmidt So let's merge this as is, and revert it once the dependency is sorted out in fourcipp,
