Align Overview UI with kit mockup: adaptive Reference card, TickerHeader hierarchy, chart width

- StatsCard filters null ratio rows; shows '· Statement data incomplete' note instead of wall of Unavailable
- TickerHeader restructured to match kit: symbol (64px display) dominant beside company name (24px italic), sector label above, chips below
- Fix broken --fs-56 token in company name clamp → --fs-64
- Chart fills full panel width via .psm-chart-frame .chart { width: 100% }
