feat(#21): support selected telegram topics for schedules

Route new schedules to an existing forum topic when /newsession is sent inside one, create bot-owned topics only from the forum root, and keep group notifications/dashboard updates threaded to the stored topic.

Persist topic ownership so deletion only removes empty bot-created topics, add topic routing tests and smoke coverage, and bump release metadata to 1.14.0.

 - **⚡ Быстрые повторы расписания**: Для регулярной кампании можно указать одну дату, количество игр и интервал, а бот сам развернёт повторяющийся batch.
 - **✋ Интерактивная запись и выход**: Игроки записываются на конкретные даты и самостоятельно снимают запись нажатием одной кнопки.
 - **👥 Лимит мест и лист ожидания**: ГМ задаёт максимальный состав, бот не переполняет сессию, автоматически ведёт очередь ожидания и освобождённое место отдаёт первому ожидающему.
-- **📁 Поддержка Форумов (Telegram Topics)**: Бот автоматически создает тему во вложенных чатах Telegram под каждую новую пачку игр.
+- **📁 Поддержка Форумов (Telegram Topics)**: Если `/newsession` запущен в теме форума Telegram, расписание и групповые уведомления остаются в этой теме; при запуске из корня форума бот создает отдельную тему и сообщает о необходимости прав admin/Manage Topics, если их не хватает.
 - **❌ Управление сессиями**: Owner и назначенные co-GM могут создавать, отменять, удалять и переносить игры из Telegram через `/listsessions`; публичный пост записи показывает только кнопки игроков.
 - **🔄 Голосование за перенос**: Быстрый поиск свободного места с через свободное недель и кнопками новых времени и дедлайном.
 - **🔔 Уведомления**: Игрок получают за 24 часа, напоминание за 1 час, ссылку перед игрой, отмены и переносы; групповые уведомления при этом остаются.
