Add persistent storage for distinct ID in logging service

- Introduce `storeDistinctId` function to update global state with new ID
- Modify `initializeDistinctId` to set up persistent storage callback
- Update `setDistinctId` to persist changes to global state
- Ensures telemetry distinct ID survives application restarts
