Mobile: public-facing pages (landing + login)

Login view:
- Remove `margin-left: calc(-1 * var(--sidebar-width))` from the
  centering wrapper. It was a hack to compensate for the sidebar
  offset, but app.js already zeros the app margin on the login
  route. On mobile this was pushing the login card ~240px off
  the left edge of the viewport.
- Use min-height + padding so the card breathes on short screens.
- Drop inline font-size:11px on the support-token input so the
  global .input 16px mobile rule applies (iOS focus-zoom prevention).

app.js:
- Hide the mobile hamburger button on the login route; it has no
  function there since the sidebar is already hidden.

Landing page:
- Scope the old blanket `.nav-links { display: none }` to hide only
  the section anchors + secondary Sign In button, so the primary
  "Start Free Trial" CTA stays visible on mobile.
- Wrap the 5-column Compare table in a horizontal-scroll container
  and set min-width:560px so it scrolls instead of overflowing
  the page.
- Add min-height:44px to .btn on mobile, tighten section padding
  to 16px (from 24px) so content doesn't feel cramped against
  the viewport edge.
