MCP custom pages: show_in_sidebar + постоянная ссылка для закладок

- create_custom_page: параметр show_in_sidebar (default true); результат содержит
  url (/pages/<slug>) и bookmark_url (полный URL) — страницу можно сразу добавить в закладки
- update_custom_page: параметр show_in_sidebar — скрыть/показать в боковом меню без удаления;
  результат также отдаёт url/bookmark_url
- В UI (Боты → JS Страницы) переключатель «Показывать в боковом меню» и ссылка /pages/<slug>
  уже были; сайдбар фильтрует по showInSidebar
