Lock Date of Birth After Membership Purchase

I’d like to suggest a feature enhancement to help maintain the integrity of our membership structure. Currently, members are able to edit their date of birth even after purchasing a membership. This creates the possibility for someone to purchase a junior membership and then update their date of birth afterwards, which undermines the system.

To prevent this, I recommend that once a membership has been purchased, the date of birth field should be locked from editing. If a genuine correction is needed, members could contact the club administrator to make the change on their behalf.
