chore: re-trigger SOP after memory-consultat typo fix

Add missing role="alert" and aria-live="assertive" to error state
banners in three components. WCAG 4.1.3 requires that status and error
messages be programmatically determinable via aria-live regions so
screen readers announce them immediately.

Changes:
- ChatTab.tsx: displayError banner — was missing role/aria-live
- ActivityTab.tsx: error banner — was missing role/aria-live
- AuditTrailPanel.tsx: error banner — had role="alert" but missing aria-live
