Adds an optional roster.json (set of allowed student IDs) loaded at startup. add_participant() raises StudentIdNotInRoster when the gate is on and the supplied id is not present; route returns 403 with a clear message and logs a roster_reject audit event. Names are NOT checked against the roster: the join form asks for a current name as a soft deterrent, but the only hard check is the id. Includes a deploy/build_roster.py helper that turns class_register attendance.xlsx into roster.json. Bootstrap env file now exports QUIZ_ROSTER_PATH; missing file disables the gate (legacy behaviour). Also drops the user-facing "The cookie is per-device." line from the join card — students don't need to know the implementation; replaced with "Enter your registered student ID and your current full name."
