feat: Decision Intelligence simplification pass

Phase 1 — MatchDetail: collapse from 11 panels to 3 visible sections
(Warum dieser Match? / Nächste Aktion / toggle). All analysis panels
(ScoreBreakdown, Risk, MissingData, NeedAlignment, Location, Tradeoffs,
FutureAvailabilityContext) hidden behind "Vollständige Analyse anzeigen".
Removes 2-column sidebar layout for cleaner single-column reading flow.

Phase 2 — Supply Dashboard: replace data quality KPIs with demand
intelligence. Hero now shows "Starke Match-Anfragen", active properties,
and Zukunftssignale count. Top 4 matches listed with score + reason +
next action. Data quality demoted to secondary collapsed notice.

Phase 3 — Future Availability: add informational banner above the results
feed when Zukunftssignale are present. Framed as professional market
intelligence (contract expiries, construction signals) not as risk.
Removed Zukunftssignal from DecisionContextPanel risks array.

Phase 4 — Naming: standardise RESULT_TYPE_META to "Verifiziertes Objekt" /
"Externes Angebot" / "Maison Work" / "Zukunftssignal" across all screens.
EXTERNAL_MARKET gets distinct amber color (#d97706). Remove Gold/Silver/
Bronze tier label from match score badge — only the % number is shown.
