Subject: [PATCH] fix(eink): gate Lemon print path on _text_sz == 1

setTextSize(2/3) switches GFX to non-Lemon fonts (built-in scaled or
FreeSans18pt). The Lemon path bypassed GFX entirely and rendered glyphs
at size 1 scale, shrinking splash version and clock when Lemon font
was active.

Refresh CODE_REVIEW.md: remove resolved issues (signed-int timing vars,
abs() no-op, XBM CRC, loadPrefs nesting, lock-screen LPP thrash, reply
prefix raw UTF-8), add new findings (upstream-merge surface, virtual
width()/height() per glyph, page_order sentinel), list enhancement
ideas.
