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()
Keep two separate stores to accomplish per-profile sharing:
- Local store, where to push updates manually (save/remove/search)
- Remote iCloud store, where to pull updates from
A profile can be added/removed to/from the iCloud store so that other
devices can push/pull updates to it.
Consequently, updates to the iCloud store will NEVER cause a profile
deletion. Once removed, the profile will stay locally.
