feat: soft factor enrichment from Swiss location intelligence

When property has no soft factor data, estimate from location:
- 18 location rules covering CH cities/districts (Zürich quartiers,
  Zug tax haven, Bern, Basel, Genf, Lausanne, Luzern, Winterthur,
  logistics hubs) + generic CH fallback
- Estimated factors marked with 'estimated: true' on ScoreFactor
- ScoreBreakdownPanel shows purple 'Schätzung' badge on estimated rows
- Scoring engine: neutral 50 only if no location match found
