feat(students): аватары в списке студентов с превью и лайтбоксом

Круглый аватар слева от поля имени: миниатюра главного фото через thumbSrc, иначе инициалы. Клик по фото открывает imgModal с полным размером, клик по пустому — карточку профиля для загрузки. Аватар синхронизируется после загрузки, смены и удаления фото.
