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)
From an engineers perspective, whenever specifying colors from now on we should use the form:
```
color: rgb(var(--tone-red-500));
```
Please note:
- Use rgb. This lets us do this like rgb(var(--tone-red-500) / 10%) so we can use a 10% opacity red-500 if we ever need to whilst still making use of our color tokens.
- Use --tone-colorName-000 (so the prefix tone). Previously we could use a mix of --gray-500: $gray-500 (note the left hand CSS prop and right hand SASS var) for the things we need to theme currently. As we no longer use SASS we can't do --gray-500: --gray-500, so we now do --tone-gray-500: --gray-500.
Just for clarity after that, whenever specifying a color anywhere, use rgb and --tone. There is only one reason where you might not use tone, and that is if you never want a color to be affected by a theme (for example a background shadow probably always should use --black)
There are a 2 or 3 left for the code editor, plus our custom-query values
