fix: extract tkinter from Python installer via 7z, fix NSIS icon path

- Replace nuget approach (doesn't contain tkinter) with extracting
  from the official Python amd64.exe installer using 7z
- Remove MUI_ICON/MUI_UNICON (no .ico file available, use NSIS default)
- Add p7zip-full to CI dependencies
