Walkthrough

The appointment success page now separates loading from missing appointment data, shows a not-found state with navigation to patient home, and triggers error notifications from useEffect.

Changes

Appointment success error recovery

Layer / File(s)	Summary
Loading and missing appointment recovery src/pages/PublicAppointments/Success.tsx	The component shows loading only while the query loads. Missing appointment data now renders a not-found state with navigation to /patient/home. Error notifications run in useEffect, and the validated patient name is accessed without optional chaining.

In `@src/pages/PublicAppointments/Success.tsx`:
- Around line 56-57: Add aria-hidden="true" to the decorative icon wrapper div
in the Success component, leaving the adjacent error heading and CareIcon
rendering unchanged.
- Around line 53-61: Update the conditional rendering in the Success component
so the error state is handled separately from an empty appointment result: when
error is set, render the request-error state even if appointmentData is present;
render appointment_not_found only after a successful response with no matching
appointment. Preserve the existing success rendering for usable appointment
data.
- Around line 39-43: Update the useEffect in the Success component to prevent
repeated toast.error calls when t changes while error remains truthy, using a
stable Sonner toast ID or tracking the reported error; preserve showing the
appointment_not_found message when a new error occurs.
