Mobile web Suite improvements

[Hermez-cz]

The aim is to efficiently fix the most important issues in mobile web Suite. Not everything is intended to be fixed as our mobile app will have enough features to offer a fully fledged solution for mobile users, rather than fiddling in a mobile browser in a web app.

Let's fix the breakpoint, so the elements are vertically distributed if they won't fit horizontally.

Please return the (x) into the banner, it's peeking out. And please make sure it scales in other languages as well.

Please crop the address after the gradient, so it doesn't overflow.
The info banner should break, so the "i" will be above the text and the text will use full width.

It could fit if we center it, but low prio, as there's not so much valuable info usually in this place to be honest, especially in a potentially short term mobile-web use case.

Broader issue with this pointy element, it doesn't come from the mobile use case, let's skip it in this issue.

This modal will be replaced in the next release, so let's just make sure the new one scales well.

Broader issue of rounding numbers, let's not try to solve it here. Trading use case in mobile web Suite might be pretty rare.

The "Last transactions" button is very unfortunately placed here. Can we perhaps hide it when in a mobile browser Suite? @tomasklim @jirih-stsh
