test(reconcile): align cross-branch fixture drift in v1.4.48 integration

- analytics/route.test.ts slim-summaries fixture: mock 4 $queryRaw
  calls (coverage + allTime + windowed + latest) to match the M0
  cold-fallback split shape
- dashboard-layout-section hint assertion: anchor on the new L9
  shortened German copy ("Pfeiltasten Hoch/Runter") instead of the
  pre-v1.4.48 phrase
