feat(calendar): пакет функционала — событие 1:1 с веб, вложения, повторение, шаринг, free/busy

- Русские месяцы в шапке; нативный DatePickerDialog (material3 крашился) - 403 при PUT события: учёт supported-calendar-component-set (VTODO-коллекции не принимают VEVENT) + sabre-precondition в тексте ошибки - Окно события по _calendar-edit-full-fields.css: pill-поля, крестик, зелёная галочка-сохранение, нативные пикеры даты/времени, высота 94% экрана - Talk-беседа к событию: выбор существующей / создание публичной|приватной - Вложения (ATTACH+FILENAME/FMTTYPE): «из файлов» (WebDAV-пикер) или загрузка с устройства в /Calendar; round-trip при редактировании события - Кастомное повторение (_calendar-repeat-modal.css): интервал+частота, дни недели кружками, окончание никогда/до даты/N раз ↔ RRULE (parse/build/описание) - Многодневные события (endDate) и несколько напоминаний (VALARM list) - Управление календарём (✎ в сайдбаре): PROPPATCH имя/цвет, DELETE, шаринг через DAV oc:invite + OCS sharees (польз./группы, чтение/редакт.) - Discard-диалог при закрытии редактора с несохранёнными изменениями - Занятость участников: iTIP VFREEBUSY через DAV outbox, конфликты красным
