feat: role-aware UX, market intelligence, score fix & layout scroll

- Role-based workspace access: Property Manager gets Supply+Demand,
  Operations restricted to Super Admin + Reviewer only
- Root redirect routes each persona to their first workspace
- Match Center: replaced 3-panel with auto-sorted flat list + drawer
- AI Search: unified form with dual-action (Jetzt suchen / Als Suchprofil speichern)
- CompareTray hidden on non-Demand routes; Vergleichen removed from Supply
- LocationIntelligencePanel: city KPIs, rent trends, soft factors, comparables
- NegotiationInsightsPanel: price positioning, active demand, selling arguments
- scoreCalculator: cap hardMatchScore and softFactorScore to max 100
- Layout: add display:flex to overflow:hidden wrappers so inner scroll works
  (MatchCenter drawer, MarketIntelligence, SourceMonitoring, SignalPipeline)
