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()
Mainly:
- Aggregate shared/mock entities in less scattered files
- Review package dependencies
Also:
- Decouple ProfileRepository from Core Data Repository in UtilsLibrary
(filters done by ProfileManager)
