fix: remove --host from npm run server command

Running `vite --host` exposes the dev server on all interfaces. However,
we should expose it on all interfaces only when `HOST` is set to `0.0.0.0`.
Otherwise, we should assume the user wants to bind to a host of their choice
and not expose the server on the network.
