Note

Low Risk
Test-only changes plus removal of a dev dependency; risk is limited to potential timer-mocking differences causing flaky/changed test behavior.

Overview
Replaces Sinon-based fake timers in AnalyticsDataRegulationService.test.ts with Jest timers, updating retry/degraded/circuit-breaker tests to advance timers via jest.advanceTimersToNextTimerAsync / jest.advanceTimersByTime and managing lifecycle with jest.useFakeTimers/jest.useRealTimers.

Drops sinon from analytics-data-regulation-controller dev dependencies (and lockfile), reducing the test-only dependency surface without changing production code.
