Update lock inspector modal example to "Senior inspector requested" and avoid suggesting lock for requests

Users want the example text on the lock inspector modal changed to something like 'Senior inspector requested' instead of wording that suggests locking for requests. The intended workflow is to use the request star for requests (which auto-locks); the lock modal should not prompt users to use it for requests, so the example should reflect a different reason such as senior inspector requested.

Why it matters: Clear, correct guidance in the modal prevents schedulers from using the wrong workflow and keeps request handling consistent.
