Various CSS tweaks/HTML cleanup around upstreams (but impacts other 'rows')
- Prefer {{tooltip}} to <Tooltip>
- Removed some now unnecessary spans
- Stop using an empty class="" for styling purposes.
- Renamed any classes used to identify response properties to follow the exact property name but kebab-cased.
- Fixed up the alignment of things in the rows when used with a 'tiny copy button' (see screengrab) which was minus positioning and knocking things out (pending a proper refactor of our copy button CSS which is from the very very start of things)
