prevent dispatcher-managed on-call schedules from being overwritten by HCM FFS Integration

Summary:

Hi Community,

We are using the out-of-the-box HCM to FFS Worker Availability integration accelerator and have run into a gap we'd like the community's input on.

How the Accelerator Works (Our Understanding)

The accelerator follows a delete-and-recreate pattern for both work schedules and internal activities:

1. Work Schedules:
   - GET /rest/ofscCore/v1/resources/{resourceId}/workSchedules — retrieves all existing work schedules for the resource in the date range.
   - DELETE /rest/ofscCore/v1/resources/{resourceId}/workSchedules/{scheduleItemId} — deletes ALL retrieved schedules.
   - POST /rest/ofscCore/v1/resources/{resourceId}/workSchedules — recreates schedules based on HCM shift data fetched via the workerAvailability API.
