Edit Family Name

Value Proposition

As a family member,

I want to edit the family name,

so that i can update the changed family name

When the user navigates to the family page, the user should see an option(edit pen icon) to edit the family name.
When the user clicks on edit pen icon, modal window should open up with the pre-filled family name and an "Update" button.
Upon clicking "Update" button the app should validate that the family name is not empty, and display appropriate validation message if it is.
Upon successful updation, confirmation message "Family name updated" has to be displayed.

[ ] create a branch feature/editFamilyName.
[ ] design the UI for the edit family name form and implement validation logic for the family name.
[ ] implement the backend API to update the family name.
[ ] integrate the front-end form with the backend API
