Add separate English/Korean font selection to font settings menu

config.font is set via wezterm.font_with_fallback({ primary, korean }),
a multi-line block that the existing single-line set_config_value
can't touch. Added get_current_fonts (reads both font names straight
out of the config file text, for display) and set_fonts (replaces the
whole font_with_fallback body in one shot, lazy-matched between the
"{" and the closing "})"), plus two new font settings menu entries
("영어 폰트" / "한글 폰트") that prompt for one name at a time while
keeping the other font unchanged.
