test(medium): Refactor useWorkoutSession for Zones, Auto-Pause, and Throttling

[arii]

Description

This PR addresses regressions and UX issues in useWorkoutSession:

1. HR Zones: Re-implemented timeInZones calculation and persistence within the hook state to ensure analytics features work correctly in real-time.
2. Auto-Pause: Added logic to automatically transition a 'running' session to 'paused' upon page load if the last activity was more than 1 minute ago, preventing incorrect duration accumulation.
3. Throttling: Reduced the UI flush interval from 5s to 1s to provide a more responsive interface.
4. Performance: Stabilized startWorkout callback to prevent unnecessary re-renders in consumer components (ConnectPage).
5. Tests: Updated and fixed useWorkoutSession.test.ts to verify these changes.
