Looks much nicer with Lighter background and rounded borders on dashboard (see video)

Looks much nicer and cleaner with pretty much the same styling as the main pages

I just did this:

• border: 1px solid rgba(0, 0, 0, 0.1)
• border-radius: 5px;

I think we could also do with slightly reducing the spacing, but didn't know how to do that easily. I think we should also make the rounding a bit bigger, and consistent on all the pages (i.e. 5px on all tiles).
