WIP: эмодзи-пикер (Telegram-набор) — чекпоинт незавершённой работы

- Эмодзи-пикер: js/components/emoji-picker.js + каталог telegram-emoji-*.js
  (smileys/people/animals_nature/food_drink/travel_places/activity/objects/
  symbols/flags) + 631 ассет в assets/emoji (7.2 МБ).
- Интеграция пикера: chat-view.js, app.js, index.html, styles/components.css.
- Дев-скрипты генерации превью + THIRD_PARTY_NOTICES.
- Работа НЕ завершена (WIP), сохранено как чекпоинт. С origin (+56) пока НЕ
  мержится — большой мерж будет после завершения, отдельным шагом.
- VERSION: client 1.2.263.
