SVG was using fixed width/height attributes causing clipping in
smaller containers. Now uses viewBox for coordinate system and
w-full h-full classes to fill container properly.

When container restarts, backend resets to default 5s interval but
frontend still shows the user's stored preference from localStorage.
Now on SSE connect, frontend pushes its stored refresh rate to the
backend, ensuring they stay in sync after container rebuilds.
