feat: self-host all external assets + larger base font

- Vendor Google Fonts: 23 woff2 + localized fonts.css under
  public/fonts/, referenced via /fonts/fonts.css. Drop the
  googleapis/gstatic preconnects and the (now unused) Font Awesome
  CDN link. No runtime external resource requests remain.
- Dockerfile copies public/fonts into the nginx image.
- html base font-size 16 -> 17px (all rem UI text scales up slightly).
