Align patrol delete module naming

Rename the patrol deletion implementation and browser helper scripts away from the generic product name so the filesystem matches the queued patrol-delete task domain. Update imports, script loading, and tests to use the patrol_delete module path.

Constraint: Existing task class remains ProductTask to avoid broad API churn beyond the requested file and script naming

Rejected: Rename ProductTask class now | would expand the change into a larger API update across tests and task dispatch

Confidence: high

Scope-risk: narrow

Directive: Keep patrol-delete script paths under app/amazon/scripts/patrol_delete when adding new helper scripts

Tested: uv run pytest tests/test_product.py

Not-tested: Remote push before this commit due previous SSH publickey failure
