feat(dashboard): pannello COMBO cross-venue (TP01 Deribit + GTAA IB)

Aggiunge alla dashboard la sezione "COMBO DEPLOYABLE — cross-venue (paper)": equity paper forward
del blend 50/50 TP01+GTAA (da data/paper_combo/state.json) + posizioni azionabili IB correnti
(gtaa_weights: peso ETF + cash, asof). Nota onesta: paper rischio-zero, Sharpe ~1.5 ottimistico, il
robusto e' la diversificazione (corr 0.21, DD dimezzato); XS01/VRP01 esclusi (STAT-MODE).
Container ricostruito (codice baked nell'immagine).
