theme: build on the shared bread-theme stylesheet

build_css() now starts from bread_theme::stylesheet(palette) and appends only
breadpad/breadman-specific components. This unifies fonts, palette, and generic
widgets with the rest of the ecosystem and fixes the colour mapping (overlay is
now color7, matching every other app, not color0). Bump bread-theme to v0.2.6.
