data display settings

[kunkoala]

Description

Made a settings menu above data cards for the number display settings. Toggle between absolute and relative values (infections per 100k pop), and total number, 1d new infection, 7d new infection. Though the 1D and 7D data still uses the total number of infected.

Design Decisions

Put a settings button that shows a settings popover for the number display when clicked.

Looks good code wise.
Design wise I'd like to have the info chip next to the settings cog as a small info tag. otherwise it's quite removed and unintuitive.
I think it should also be part of the settings button, clicking the chip should also open the relevant setting popover.

⚠️ Also make sure this shows up somewhere in the export in #428 depending on which you merge first.
