feat: Reminder Manager + Schattenmarkt-Freigabe + mock data overhaul

- Add Reminder Manager page (/supply/reminder-manager) with KPI bar,
  filter bar, list/card feed, and detail drawer (7 sections incl.
  activity log, snooze, complete, dismiss actions)
- Add Schattenmarkt-Freigabe toggle on PropertyDetailView: Verwaltung
  can opt-in properties for early market exposure before contract expiry
- Auto-generate FutureSignal cards via useSchattenmarktSignals hook
  when leaseEndDate - leadTimeMonths <= MOCK_TODAY
- Fix useUnifiedResults: use property.resultType as fallback (was
  defaulting everything to VERIFIED_PORTFOLIO)
- Fix demand Results: hide VERIFIED_PORTFOLIO from non-manager users
  even when showOwnProperties toggle was previously enabled
- Fix AppShell: redirect to allowed workspace on user role switch
- Fix 3 wrong match scores (match-002: 93→62, match-009: 86→55,
  match-017: 87→52)
- Add 7 new match records (match-050–056) for need-001, need-002,
  need-011
- Add need-011 (Retail Bern Innenstadt)
- Add prop-031–036 (EXTERNAL_MARKET / MAISON_WORK / FUTURE_AVAILABILITY)
- Fix duplicate image URLs across all properties
- Add signal-011 (Bern Altstadt, Mode Boutique) + propertyId to
  signal-001
