Description

Phase 3 analytics migration (Batch 3-14): migrate Legal/Onboarding's terms-of-use utilities from MetaMetrics.getInstance() to the new analytics system.

Reason: Deprecate MetaMetrics in favour of the shared analytics utility and AnalyticsController.

Changes: termsOfUse.ts now uses analytics.trackEvent() and AnalyticsEventBuilder from app/util/analytics; test mocks updated to mock the analytics utility instead of MetaMetrics.getInstance().

Manual testing steps

Feature: Legal/Onboarding analytics

  Scenario: user triggers a terms of use flow event
    Given app is open and user has not yet accepted terms of use

    When user performs an action that triggers analytics (e.g. terms of use shown, terms accepted)
    Then the event is tracked on Mixpanel
