refactor(web): HTML cleanup — remove inline styles, add script tags for i18n and cv-matcher

- Remove all 7 inline style="display:none;" attributes from loaders/cookie elements
  (now handled by CSS with .loader-overlay { display: none } and
  .loader-overlay.loader-visible { display: flex })
- Remove orphan footer-legal class (unused in CSS) from footer-links divs
- Add <script src="/js/i18n.js"></script> before main.js on both pages
- Add <script src="/js/cv-matcher.js"></script> after main.js on cv-matcher page

jQuery 4.0 now detects CSS display:none correctly via getComputedStyle,
so class-based visibility (.loader-visible) works seamlessly.

Closes #31
