Garry Tan ffb064afda feat(ui): wire security banner to security_event + interactivity
Adds showSecurityBanner() and hideSecurityBanner() plus the addChatEntry
routing for entry.type === 'security_event'. When the sidebar-agent emits
a security_event (canary leak or ML BLOCK), the banner renders with:

  * Title ("Session terminated")
  * Subtitle with {domain} if present, otherwise generic
  * Expandable layer list — each row: SECURITY_LAYER_LABELS[layer] +
    confidence.toFixed(2) in mono. Readable + auditable — user can see
    which layer fired at what score

Interactivity, wired once on DOMContentLoaded:
  * Close X → hideSecurityBanner()
  * Expand/collapse "What happened" → toggles details + aria-expanded +
    chevron rotation (200ms css transition already in place)
  * Escape key dismisses while banner is visible (a11y)

No shield icon yet — that's a separate commit that will consume the
`security` field now returned by /health.
