ui: Improve layout of node cards on large and small screens (#4761)
1. The grid based unhealthy cards are now clamped to only four wide
maximum. This means that on larger screen the cards are much wider
meaning you can view more information. Grid gutters are also clamped at
a certain ideal width screen, remaining responsive for anything below
this.

2. The healthy node columns are finally responsive following the same
column rules as unhealthy nodes
