Replaces "Schattenmarkt" branding with professional Future Availability Intelligence throughout the UI. Two distinct card types: Pre-Market (LEASE_EXPIRY + verified, green accent) and Market Signal (probabilistic, blue accent). Professioneller Data-Header replaces dark purple gradient. New detail panel sections: Erkannte Marktindikatoren, Strategische Interpretation, Bestätigt/Nicht bestätigt. All 15 mock signals enriched with concrete Swiss CRE market indicators and strategic interpretations. Signal quality shown as 4-dot indicator (Hoch/Mittel/Niedrig).
