[PM-7541] Move Last Desktop Settings

[justindbaur]

Type of change

- [ ] Bug fix
- [ ] New feature development
- [x] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

We had 3 settings left to migrate to the desktop settings service, this allows us to delete StateService in the main process of desktop altogether (exciting!).
