Adopt StateStoreViewModelV2 in the remaining settings screens. (#4158)

* Move the AuthenticationStartScreen into the Authentication directory. * Commit the updated Sentry license. No idea why they dropped the 2024 🤷‍♂️ * Use StateStoreViewModelV2 in BugReportScreen. * Use StateStoreViewModelV2 in UserDetailsEditScreen. * Use StateStoreViewModelV2 in NotificationSettingsScreen. * Use StateStoreViewModelV2 in NotificationSettingsEditScreen. * Use StateStoreViewModelV2 in LegalInformationScreen. * Use StateStoreViewModelV2 in LogViewerScreen. * Use StateStoreViewModelV2 in AnalyticsSettingsScreen. * Rename AdvancedSettingsScreen directory. * Use StateStoreViewModelV2 in EncryptionResetScreen. * Use StateStoreViewModelV2 in EncryptionResetPasswordScreen. * Use StateStoreViewModelV2 in SecureBackup…Screens. * Use StateStoreViewModelV2 in LoginScreen. Seems this one was ignored waiting on the fulfillment transitionValues implementation. * Use StateStoreViewModelV2 in DeactivateAccountScreen. * Move DeactivateAccountScreen into the Settings directory.
