Publish to apple App store

I just need an Apple dev license, and need to modify the tauri CI action.

Before I do this, I want the tauri build to be better. A better onboarding, including the build files, make sure auto-update works... Lots of stuff to do.

• Invite handler checks: check availability, create drive - registration / onboarding #225
• Auto-update / self-update binaries #158
