#62 — Global error boundary + query error fallback UI

[IbrahimIjai]

Description:
Add a React error boundary in app/providers/index.tsx that catches render errors. Add onError handler to QueryClient that:

• Logs to console in dev
• Shows a Sonner toast for user-visible query failures (not auth errors which are silently retried)

Acceptance criteria:

• Unhandled query error → red toast with parseSorobanError message
• Error boundary renders a fallback <ErrorPage /> with a "Reload" button
