Saving a child's email from the mobile app works again
Editing a family member in the mobile app failed the moment you tapped Save, with a "nothing to update" message, so a parent could never set or change their child's email address from their phone. The Save button now applies a new name and hands the email change to the same verified flow the website uses, showing the invite code or confirmation right in the sheet. A member's role is shown but no longer editable after they are added, matching the website.
