update table styles

[michellescripts]

This PR updates our existing Table/Data Table styles to match the new look/feel introduced by Unified Resources more closely. It is intended as a "bridge" between the old styles and the new, not a full implementation of the new UI.

This PR does not include the new FilterPanel. The styles are applied to the current layouts as closely as possible (i.e., pagination is functionally the same as before and matches the new filter panel text). Eventually, we may replace pagination with FilterPanel (adding new sort/filter etc. functionality), move the cluster select into that panel and introduce Card views (as applicable).

sorry i got reminded of this from recent activity.

lgtm, non-blocking nits (these are fairly new additions):

the header is transparent:

when you hover over these rows, it does a slight jump:
