{{--
    Ports app/Views/adviser/students/index.php (legacy) — see the Phase 44
    plan. The "Добавить" (add student) modal posts to the shared
    /add_student.php endpoint. This used to be a confirmed dead/broken
    feature: the endpoint (StudentProfileController::store(), guarded by
    guardCanCreateStudent()) required an admin/manager role and a `password`
    field the modal didn't submit, so submitting as an adviser always failed
    with a "no permission" flash. Per the user's explicit request, advisers
    are now allowed through the guard and the modal has `password`/`iin`
    fields added to match the admin/manager form in students/index.blade.php.

    The "Формат обучения" (education_type) filter is also a confirmed no-op
    — never wired into the controller's query — preserved, not fixed.
