- Add Lemon font (LemonFont.h, LemonIcons.h) to the standard build
alongside the Adafruit built-in font; ~101 KB added to flash
- SH1106Display: add _use_lemon flag + setLemonFont(bool) to switch
at runtime; print() and getTextWidth() use Lemon path when active;
translateUTF8ToBlocks() passes UTF-8 through unchanged (Lemon supports
full Unicode U+0020-U+04FF) vs transliterating for the default font
- DisplayDriver: add getCharWidth()/getLineHeight() virtuals (defaults 6/8);
SH1106Display returns 5/9 for Lemon, 6/8 for default; add setLemonFont()
no-op virtual; fix orphaned UTF-8 leading byte in drawTextEllipsized
- FullscreenMsgView: replace fixed-char-count word-wrap with pixel-accurate
wrap using display.getTextWidth(); use getLineHeight() for spacing so
Lemon (9 px) and default (8 px) both render correctly
- NodePrefs: add use_lemon_font field (0=default, 1=Lemon)
- SettingsScreen: add "Font" item in Display section (Default / Lemon),
calls UITask::applyFont() on change
- UITask: add applyFont() that calls display->setLemonFont(use_lemon_font);
called at startup (begin()) and when the setting changes
