fix(marketing): A-2.8b — Loi 25 badge contrast (WCAG AA) + stale docstring

- Loi 25 article number badges (Art. 3.3, 3.5, 14): change from
  `grad-bg text-white text-xs font-black` to `bg-brand-navy text-white
  text-xs font-black`. White-on-grad-bg failed AA on the cyan/green
  portion of the gradient (~2:1 contrast); solid navy gives ~16:1.
- Update routes.py module docstring to past tense (A-2.8b is now done).
- Add regression assertion ensuring badges use solid navy, not grad-bg.
