Extract duplicated styles into shared molecules and color atoms

Move .score, .status, .add-bar and .btn-accent molecules into app.css
and replace BEM color modifiers with bare atoms (bg-success, bg-accent,
bg-danger, bg-accent-soft, text-accent, text-white). Rename the
category-specific cat-add-bar to add-bar and the groceries page's
sticky autocomplete bar to grocery-add-bar to avoid the collision.
Cuts dcd duplicate lines from 1288 to 780.
