fix(site-finder): correct POI-score mock shape+values, routing empty assert (#1486 review)

- Rename top_poi → items in poi-score.json to match PoiScoreResponse TS type
  (mock was cast as PoiScoreResponse but had wrong field name → items undefined
  at runtime in MOCK_POI_SCORE mode → PoiList2Gis crashed at [...items].sort)
- Recompute all score_contribution values using backend formula
  (weight / _MAX_STRAIGHT_SCORE * 100, _MAX_STRAIGHT_SCORE=0.315) and
  poi_weighted_score=19.9 (was 72, which was inconsistent with the new normalization)
- Add assert result.poi_weighted_score == 0.0 to test_routing_decay_empty_db
  to match the straight-line empty-db assertion
- Remove stale comment in PoiList2Gis.tsx saying normalization needs fixing in
  site-finder-api.ts (already done backend-side in this PR)
