Pin React to 19.2.3 (exact version RN 0.85.3's bundled renderer
requires — 19.2.6 caused "Cannot read property 'default' of
undefined" crash at getPaperRenderer).
Auth: fall back to parsing user info from Cognito ID token when
backend API is unreachable, removing the hard dependency on
localhost:5000 for credential login.
UI fixes:
- Safe area insets on Settings screen (top edge was missing)
- Separate refresh indicator from filter-triggered loading on
proposal queue (chips no longer trigger pull-to-refresh animation)
- Dashboard welcome shows first name instead of full email
- Dashboard/AdminDashboard remove duplicate top safe area when
navigation header already provides it
- Service category selector uses wrapping chips instead of
cramped SegmentedButtons
- Add ErrorBoundary to App root for crash visibility
