feat: UC-A/B/C demo — 50 mock properties, district scoring, gold/silver cards visible

- Add 50 mock properties (prop-050–099) tuned for UC-A (Fahrradhändler RETAIL),
  UC-B (Umzugsfirma OFFICE Zürich-West) and UC-C (Vermögensverwalter PREMIUM)
- District-aware scoreLocation: district match→100, city-only→70 when need
  specifies districts, canton→60, no match→35; fixes UC-C prop-001 over-scoring
- mustHaveScorer: add klimatisierung keyword; parking minimum count logic
- Soft factor scale fix: integer 0–100 values no longer multiplied ×100
- footfall: map passerbyFrequency string (HIGH→85, MEDIUM_HIGH→68…) before
  enrichment fallback so RETAIL properties score correctly
- Parser: Kreis list extraction ("Kreis 3, 4, 5, und 8" → 4 district entries),
  neighbourhood→district map (Seefeld, Bahnhofstrasse), prestige signals
- Results: remove VERIFIED_PORTFOLIO role gate — all users see portfolio cards,
  enabling gold (85+) and silver (70–84) cards for every demo use case
- Fix flash of wrong cards on NeedBuilder nav (effectiveNeedId not activeNeed?.id)
- needs.ts: UC-A preferredLocations now includes Kreis 3/4/5/8 entries
