There are two issues observed on the Beneficiary/Household screen:

1. Incorrect Toast Message:
   The toast message displaying “X family members are already registered” is showing incorrect count.
   • Example: Household has 6 members, but toast shows “2 family members already registered”
   • In another case, it shows 5 registered while total members are still 6
     This indicates mismatch in calculation or incorrect data being passed.
2. UI Issue (Color Inconsistency):
   The purple color used in the button (Add Member) does not match the overall application theme, causing inconsistent UI and poor user experience.

Steps to Reproduce:

1. Navigate to All Beneficiaries List
2. Try to add/view members
3. Observe the toast message
4. Also observe the UI color of the Add Member button/toast

Expected Result:

• Toast message should show correct count of already registered members
• UI colors should be consistent with application theme

Actual Result:

• Toast message shows incorrect member count
• Purple color is inconsistent with app theme and looks visually incorrect
