Apply Finlio cream/terracotta design system

Re-theme dashboard, suivi, plan, and flux pages plus nav from the
claude.ai/design import: warm cream/terracotta/olive palette, pill
nav/buttons/inputs, Caprasimo display font for headings. Dark mode
variant derived to hold the existing WCAG AA contrast ratios since
the import only specified light.
