Manage Profile Screen

Form-based editor for the authenticated customer profile. Fields for first/last name, phone, photo and addresses. Submits via customerProfileServiceProvider.updatePersonInfo.

1. Reads current data from customerProfileServiceProvider.
2. User edits fields; submit builds a CustomerProfileRequest with only the diff.
3. updatePersonInfo throws → SnackBar with message; succeeds → pop with success snackbar.

• Avatar upload is handled separately (multipart) and only persists if the user also taps Save afterwards.
• Phone field is optional — empty string is dropped from the request so backend doesn't null it out.
• Form is unmounted aggressively on submit success; ref.mounted guard in the notifier protects against this.

Updating seller-specific fields (métiers, working hours) is in a different screen, not here.
