Fix algo filters showing both inline and dropdown at once

- Wrap inline algo buttons in a hidden/flex container so the
  parent div controls visibility instead of per-button classes
  (scoped .nav-button display:inline-block was overriding
  Tailwind's hidden class)
- Add flex-shrink-0 to logo link so it never gets squeezed out
  on narrower desktop screens
- Reduce logo-to-nav gap on md screens (gap-4) to prevent
  overflow, widen to gap-10 at lg+
