Draft: Resolve "patient search by book number and vitals api"

Summary This merge request implements the Patient Vitals Search by Book Number feature on the Volunteer Dashboard. It allows volunteers to quickly retrieve and view patient vitals data using the Book Number, directly from the dashboard.

🎯 Problem Addressed Patient vitals were previously accessible only through multiple screens, which slowed down patient handling during medical camps and increased navigation effort for volunteers.

✅ Changes Introduced Added Patient Vitals Search dashboard card Integrated Vitals API to fetch data using Book Number Displayed vitals data in a clear, structured format Included support for vitals history where available

🧩 Feature Coverage On entering a valid Book Number, the following information is displayed: Patient identifier (Book Number, Name if available) Vitals details: Blood Pressure Pulse Temperature Oxygen Saturation (if available) Recorded date & time

📈 Impact Faster access to patient vitals Reduced screen switching Improved efficiency for volunteers Better patient monitoring during camps

🧪 Testing Verified vitals retrieval with valid Book Numbers Handled empty / invalid Book Number cases Confirmed UI responsiveness and scroll behavior
