non-apps with metainfo component type of desktop application

### What Happened?

There are some compulsory components that currently have a metainfo component type of "desktop-application" even though they're not exactly apps:

- [ ] Authentication Agent
- [ ] Captive Network Assistant
- [ ] Intial Setup
- [ ] Notifications
- [ ] Welcome

### Steps to Reproduce

Change the component exclusion if statement for compulsories to include kind != DESKTOP_APPLICATION

### Expected Behavior

These components should probably not declare themselves as "desktop-application" but its unclear to me what fits better.

Should they all be generic components with no "type" field?

Should "Authentication Agent", "Captive Network Assistant", and "Notifications" be considered a "service"?
