test(e2e): no grade is carried past a no-grade inspection

Rabbsfarm (102408) must read 'Inspected · 2025' with no overall grade, and Robins Lane (104762) must say its Good was confirmed at an ungraded inspection on 18 July 2024. Both fail against staging today (no current_grade field, no confirmation line) and pass once PR #183's pipeline run and this branch are deployed.
