[FIX] FAB segnalazione/ARIA: icone FontAwesome -> SVG inline (regressione swap BI) + slot data-api-key

Icone: bug-reporter.js (nx-bell fa-bell, nx-bug fa-life-ring) + common.js ai-chat-fab/header/send
(fa-wand-magic-sparkles, fa-paper-plane) erano FA, rimosso dallo swap BI -> cerchi vuoti. Sostituite con
SVG inline (currentColor, self-contained). Verificato headless: 3 FAB renderizzano svg.
Auth widget: cablato s.dataset.apiKey <- window.NEXUS_WIDGET_API_KEY (X-API-Key gateway AgileHub, era
assente -> 401). _detectUser ora legge anche nis2_access_token. SERVE la chiave X-API-Key da AgileHub.
