fix(review): design-lite rows keep the detector's [rule-id]; the e2e detector rows point at the diff

The output template had no rule-id slot, so rows merged with checklist items
dropped the detector id (census t2, local t1). Rows now carry [rule-id]. The
fake engine's sample rows named a foreign fixture path at line 0; the e2e remaps
them to landing.html/styles.css so trials stop spending turns reconciling it.
