Мелодию-вызов перевёл с кастомного Web Audio на общий движок звуков LS.sfx: - длинный вестминстерский бой теперь в sound.js (звук lesson_start); - api.js лениво подгружает sound.js на любой странице и играет lesson_start по SSE classroom_started (вместо собственного синтезатора); - отдельный pref lessonCall + тумблер «Вызов на урок» и кнопка прослушивания в профиле (Настройки → Звуки); уважает мастер-тумблер и громкость; - lesson_start выведен из категории classroom (управляется своим тумблером); - разблокировка AudioContext по первому жесту перенесена в sound.js.
