i18n(chat): translate chat note-buffer status strings (8 languages)

The status-bar chat-buffer indicator was hardcoded English. Add semantic keys
(chat_buffer_sending[_one]/preparing/loading/ready) to the English source and
route chatBufferStatusText() through TR()+snprintf like the other counted
strings — a singular/plural pair for the send count, %d/%d for the buffer
fill. Translate all five into de/es/fr/ja/ko/pt/ru/zh (additive JSON edits,
format specifiers preserved so the runtime overlay accepts them), and rebuild
the CJK subset font for the two new glyphs (버퍼's 퍼 U+D37C, 缓冲's 冲 U+51B2).
