{{--
    Interstitial screen for GroupProfileController::storeStudentMembership()
    and StudentProfileController::addToGroup() when the submitted joined_at
    is today or in the past: GroupJoinBackfillService::preview() has already
    simulated what would be charged for the missed lesson days, and nothing
    has been written yet — this is a plain confirm-before-charging step, not
    a redisplay of an error. Cancelling just navigates away; Подтвердить
    resubmits the same original fields plus confirmed=1 to $actionUrl, which
    is what actually creates the student_groups row and the charges (see
    GroupJoinBackfillService::commit()).

    Table styling mirrors the "Прогноз" tab (resources/views/charges/index.blade.php).
