Subject: [PATCH] fix(exam): lock the exam form to CHOICE when administration
 is Online
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Matches the new backend rule (online_exam_requires_choice_form) — picking
Online in the exam form now auto-sets Form to Choice and disables that
field with an explanatory hint, instead of letting the user pick Essay
and only finding out at save time.
