refactor: resolve bundled font/icon dirs via helpers, not hardcoded paths

Add fonts_dir()/icons_dir() helpers ($CCE_FONTS_DIR / $CCE_ICONS_DIR with
$HOME-based fallbacks) and route the remaining hardcoded /home/lsgalante font
and cce-icons SVG paths through them (text_box font db, keybinds remove icon).
