Note

High Risk
High risk because it replaces the source of truth for notification enablement from Trigger API config to Authenticated User Storage, changing initialization and enable/disable flows and introducing breaking option/type changes that can affect user notification state.

Overview
Switches notification settings to Authenticated User Storage (AUS) as the source of truth. NotificationServicesController now reads/writes AUS NotificationPreferences via new required messenger actions, and derives enabled accounts for push + on-chain notification fetching from walletActivity.accounts rather than Trigger API config.

Adds first-time preference initialization and new options. When AUS preferences are missing (null), createOnChainTriggers seeds a full preferences blob (wallet activity seeded from Trigger API state with “enable all” first-time fallback; marketing seeded from hasMarketingConsent and new productAnnouncementEnabled; perps/social defaults added). The unused resetNotifications option is removed (breaking).

Updates types/tests/mocks accordingly. @metamask/authenticated-user-storage notification preference fields replace enabled with inAppNotificationsEnabled/pushNotificationsEnabled, and Trigger API “update notifications” code/tests are removed in favor of AUS writes; package build references and exports are updated to include the new defaults.
