fix(kimi-web): disable text hyphenation and code ligatures (#1438)

Set hyphens: none (with the -webkit- prefix) on body so chat and markdown text never gain a hyphen glyph at a line break; components still control where lines wrap via word-break/overflow-wrap.

Disable the ligatures that coding fonts enable by default (liga/calt/ss01) on native code elements so code renders literally, e.g. != stays as two characters.
