Generate idempotency keys from persisted booking fields.

When a booking is promoted to BookingStatus.ACCEPTED with a status-only update, this branch leaves the existing idempotencyKey unchanged. For pending bookings, that value is null. Resolve startTime, endTime, userId, and reassignedById from args.where, merge them with changed fields, and generate the key. This also prevents keys with an undefined userId.

Update the idempotency-key generation around generateIdempotencyKey to run for
status-only updates by resolving persisted startTime, endTime, userId, and
reassignedById from args.where, then merging those values with changed fields in
args.data. Generate the key only when the required booking fields are available,
ensuring userId is not undefined and preserving explicitly updated values.
