Feature: Auto Generate Patient Book Number

Problem

Currently, patient registration depends on manual handling of book numbers, which may lead to duplication and inconsistency across modules.

Proposed Solution

Implement an automatic system to generate a unique patient book number at the time of new patient registration.

Requirements

Automatically generate a unique book number for every new patient

Ensure no duplicate book numbers are created

Display the generated book number immediately after successful registration

Use the same book number consistently across all modules:

Assign Doctor

Record Vitals

Prescription

Medicine Verification

Counseling

Patient Status

Consultation Queue

Acceptance Criteria

A book number is generated automatically on patient creation

The generated book number is unique in the database

The book number is visible on the UI after registration

All patient-related workflows work using this book number

No manual entry of book number is required
