fix(hud): apply legacy formatting codes to action bar and titles

Servers send § codes inside a component's text. Vanilla's font applies them to every literal, but the action bar, title, subtitle and boss bar names drew the component raw, so the codes showed as glyphs. Resolve them before measuring and drawing, as the sidebar already does.
