test(evals): find least-scope delivery's task by its origin chat, and stop grading reply keywords

Chat guidance says a conversation is never a parent, and the server records
the chat that created a task as originIssueId. The case required
parentId === source chat in the setup endpoint (which then refused Morgan's
check with 403), the observer and the grader, so a correct delegation could
never pass. Use originIssueId, which callers cannot set.

The worker report and confirmation checks matched keyword lists in model
output. Require a report comment from Morgan's run and a non-empty
confirmation after it; the endpoint outcome stays graded by the scope
receipt and access records.
