The dashboard was converted to material-ui in #1776.

Tables throughout the app need to be revisited and neatened

• fix table widths, currently the tables are too wide, the columns are too narrow
• the tables in Overview are currently overflowing the Expand container
• now that Add Grafana dashboard for authorities #1225 has merged, remove the restriction on displaying the grafana link in the tables for authorities
• the bar chart in the ServiceMesh table should have a greyed out bar for no meshed, not yellow
