Web layout errors on mobile devices

[CatMe0w]

On mobile devices, arrival-view may not be positioned correctly and may block the exit button.

Thanks for opening the issue! Yes, I think right now there are a few issues with the web layout.

• The instructions view should be wider. I assume it's proportional right now, but that obviously doesn't work on mobile.
• The arrival information view at the bottom includes too much detail (seconds for example are not relevant); we should ideally use the same formatting as native mobile platforms. If JS lacks good support for this, the Kotlin formatters are good inspiration since Java was similarly lacking.
