Replace charmap's bespoke tab drawing/hit-testing with mtk::draw_tab_bar /
mtk::hit_tab_bar so the top tabs match the canonical MontaukOS style used by
the Desktop Settings panel: a surface-colored bar with a bottom border, the
active tab cut out in window_bg with a 3px accent underline, active label in
accent and inactive labels in text_subtle. Tab height is now 36 (theme.tab_h).
Drops the custom hover tint (the canonical style has none).
