Resolve "feat: Auto-redirect to Assign Doctor after Patient Registration"

🚀 Merge Request: Auto-Redirect to Assign Doctor After Patient Registration

Description

Currently, after a volunteer successfully registers a new patient, the application redirects back to the landing page. To assign a doctor, the volunteer must manually navigate to the Assign Doctor page and search for the newly created patient again. This adds unnecessary steps and slows down the workflow, especially during high-volume registrations.

This MR improves the registration flow by automatically redirecting the volunteer to the Assign Doctor page immediately after a new patient is created.

---

User Story

As a volunteer, I want to be automatically redirected to the Assign Doctor screen after registering a new patient so that I can immediately assign the patient to a doctor without additional navigation.

---

Acceptance Criteria

• Trigger: Redirect occurs only after a successful Create & Register Patient action
• Feedback: Displays a success notification before redirecting
• Action: Navigates to /volunteer/assign-doctor/{book_no}
• State: Assign Doctor page loads with the newly created patient’s Book Number pre-filled or automatically selected

---

Technical Changes

• Updated PatientRegistrationPage.tsx
• Modified createPatientMutation onSuccess handler
• Added navigation to /volunteer/assign-doctor/${data.book_no}
• Introduced a short delay (~1000 ms) to allow the success toast to be visible before redirecting

---

Testing

• Verified patient creation succeeds
• Confirmed success toast is displayed
• Confirmed automatic redirect to Assign Doctor page
• Confirmed Book Number is pre-filled / auto-selected

---

Notes

This change improves volunteer efficiency and reduces unnecessary navigation during patient registration workflows.
