- Add Registration Screen. - Add Server Selection Screen. - Rename AuthenticationCoordinator to LegacyAuthenticationCoordinator. - Add AuthenticationService and RegistrationWizard. - Async extensions. - Add global white and EMS colors to the themes. - Add tests for server selection and registration screens. - Accessibility and iPad layout tweaks. - Remove MainActor from Auth Coordinators/VMs/Views. (It broke the protocol conformances so now the methods and properties are marked individually.)
