feat: add travel and room alerts, live lesson notifications, and launcher shortcuts

- Implemented travel alerts for notifying about classes in another town the evening before. - Added room alerts for notifying about room changes on the morning of the class. - Introduced live lesson notifications to provide ongoing updates during classes. - Created launcher shortcuts for quick access to today's schedule, weekly overview, search functionality, and adding new tasks. - Updated settings to manage new notification preferences and integrated them into the user interface. - Enhanced notification channels for better organization and user experience.

 - Поиск по университету: занятия преподавателя или аудитории на выбранный день.
 - Виджет «Сегодня» (Glance): текущая и следующая пара, обновляется каждые 15 минут без сети.
 - Напоминания перед парой за 5–30 минут — локальные будильники из сохранённого расписания, без push-сервера. С разрешением «Будильники и напоминания» приходят точно в срок, без него — в окне ±5 минут.
+- **Уведомления о дне** (настройки → «Уведомления о дне», тоже локальные, из сохранённого расписания):
+  - «Занятия в другом городе» — вечером накануне такого дня (18:00–21:00, по умолчанию 20:00) приходит «Завтра занятия в Полоцке» с первой парой, аудиторией и числом пар. Напоминание о первой паре этого дня, если напоминания включены, приходит раньше обычного на 0–60 минут (по умолчанию 30).
+  - «Переносы аудиторий» — утром в день переноса (6:30–8:00, по умолчанию 7:00, но не позже чем за час до пары) приходит «Сегодня перенос аудитории: 15:20 Возрастная физиология… — ауд. 100, обычно 402Н».
+  - Оба включены по умолчанию. Нажатие открывает этот день в «Расписании».
+- **Текущая пара в шторке** (выключена по умолчанию): пока идёт пара, в шторке висит уведомление — предмет, «до 11:30 · ауд. 205Г · Полоцк», следующая пара и прогресс по половинам пары из расписания звонков. На Android 16 это Live Update: в строке состояния плашка с обратным отсчётом до конца пары, на экране блокировки — само уведомление. Оно появляется по будильнику в начале пары, обновляется раз в несколько минут и само исчезает в конце.
+- **Ярлыки на иконке** (долгое нажатие): «Пары на сегодня», «Неделя», «Найти аудиторию», «Новое задание» (открывает «Планы» с выбором пары).
 - Офлайн: последнее расписание хранится на устройстве; каждые 6 часов WorkManager обновляет его, виджет и напоминания.

 **Экзамены, зачёты, консультации и защиты курсовых** попадают в «Расписание», «Календарь» и «Планы», даже если университет публикует их отдельным документом («Расписание зачетов»): `/api/timetable` (API 6) добавляет к дням семестра события сессии группы из всех документов каталога и продлевает период до последнего из них (не дальше 60 дней после семестра).
