The system does not enforce proper age validation based on family relationships.

Currently, while adding family members, it allows elder relationships (such as Father, Mother, Grandfather, Grandmother, Father-in-law, Mother-in-law, etc.) to be registered with an age less than younger members (e.g., son/daughter).

This results in logically incorrect family hierarchy data.

Steps to Reproduce

1. Register a beneficiary (e.g., Son) with age 25 years
2. Add a new family member with relationship:
   • Father / Mother / Grandfather / etc.
3. Enter age less than 25 (e.g., 20 years)
4. Submit the form

Actual Result

• System allows saving the record
• Elder family member has lower age than younger member

Expected Result

• System should enforce relationship-based age validation
• Elder roles must have greater age than dependent roles
• Proper validation message should be shown, e.g.:
  "Selected relationship requires age to be greater than existing family member"
