[harshitg927]

Describe the bug
Add new patient form in search patients tab allows negative age values.

To Reproduce
Steps to reproduce the behavior:

1. Navigate to the "Search Patients" section in the main navigation.
2. Select the "Add New patient" button
3. In the patient registration form, locate the Date of Birth field
4. Enter a negative number in the Age field
5. Observe that the system accepts negative age values without validation and the calculated year of birth is incorrectly computed based on the negative age.

Expected Behavior:

1. The system should prevent users from entering negative values in the Age field.
2. A proper validation message should be displayed when attempting to enter negative ages.
