Split AppUI into AppUI and AppUIMain to allow for a new, simplified
AppUITV target tailored for the Apple TV.
As a PoC, present a view with a list of the shared profiles.
Initial integration of providers via API:
- Generic views and modifiers for provider/server selection
- Add in OpenVPNView
- Prepare in WireGuardView
Also:
- Introduce ProfileProcessor, move IAP processing there
- Move .asModuleView() to ModuleViewModifier for proper animation
- Use .themeModal() rather than .sheet()
