{{--
    Interstitial screen for any single-group `student_groups` write that would add
    and/or remove `charges` rows (per GroupMembershipRecalcService::preview()).
    Nothing has been written yet — preview() only simulated. Cancelling just
    navigates away; Подтвердить resubmits $hidden plus confirmed=1 (and whichever
    remove_charge_ids[] the admin left checked) to $actionUrl, which is what
    GroupMembershipRecalcService::commit() actually applies.

    Shared by three call sites, distinguished only by wording/fields:
    - AdviserScheduleController::renderRecalcConfirm() — editing joined_at/end_date
    - GroupProfileController::renderRemoveRecalcConfirm() — removing a student from
      a group (admin and teacher flows both backdate end_date to yesterday)

    Originally adviser/schedule/confirm-recalc.blade.php, hardcoded to the edit-flow
    wording/fields; generalized here once a second and third call site needed the
    same screen. Styling mirrors groups/confirm-join-backfill.blade.php.
