Resolve "feat: Patient Overview Search by Book Number and Consultations"

📌 Description:

This merge request adds a Patient Overview Search by Book Number feature to the Volunteer Dashboard. Volunteers can search for a patient using their Book Number and access all consultation-related information in a single consolidated view. The overview also enables quick corrections and edits to patient and consultation data, reducing the need to navigate across multiple features.

🎯 Problem Statement:

Earlier, consultation and patient information was scattered across different sections of the application. To correct even small data entry mistakes, volunteers had to visit multiple pages, slowing down workflows and increasing friction during busy medical camps.

💡 Solution Implemented:

A Search by Book Number option has been introduced on the Volunteer Dashboard that:

• Fetches patient and consultation data in one place
• Provides a consolidated overview focused on consultations
• Enables volunteers to quickly edit and correct data without switching between multiple screens

📈 Benefits:

• Faster access to patient consultation details
• Reduced navigation across multiple features
• Quick correction of data entry errors
• Improved efficiency and smoother volunteer workflow during medical camps

✅ Checkpoints:

• Edit functionality allows quick correction of incorrect or missing data
• API integrations follow existing frontend service patterns
• TypeScript types updated to match backend API responses
• Error handling implemented for empty states and API failures
• UI layout remains consistent with the existing design system
