Justin Mitchell 4f55444f67 Add 2-bit compressed rendering for large UI fonts
Refactor UI font generation to support different rendering modes based on size. Small UI fonts (12pt) use 1-bit rendering for crisp display and reduced flash usage. Large UI fonts (14pt) now use 2-bit compressed rendering to stay smooth when scaled up on touch/high-density boards. Extract font generation logic into reusable generate_ui_font() function.
