feat: expose all 13 scoring criteria as weighting sliders

Previously only 8 of the 13 engine criteria had sliders — flexibility,
visibility, footfall, talentAccess, esg were scored using fixed defaults
with no user control. Now all 13 criteria appear in the WeightingEditor.

- needBuilder.ts: WEIGHTING_KEYS and WEIGHTING_LABELS extended to all 13
- scoreCalculator.ts: CORE array in resolveProfile now includes all 13
- need.ts: WeightingProfile interface explicit for all 13 fields
- needs.ts: all 11 mock need profiles updated with asset-type-appropriate
  weights (RETAIL needs high footfall/visibility; LOGISTICS low; OFFICE
  high talentAccess; TechStart high taxEnvironment for Zug, etc.)
