[ui] For runs targeting assets, show >1 asset in the Target column

We’ve had reports that users who launch small N numbers of assets together find the new run feed UI difficult to use, since it shows either “asset name” or “2 assets” in the Target column. This PR:

- Expands the target column a bit
- Shows as many asset / check tags as will fit in the available space, and then “X more”

The implementation of this uses a new hook `useAdjustChildVisibilityToFill`. The idea is that your component renders some reasonable max number of tags (10) and a more tag, and the hook uses a resize observer + layout effect to show/hide the tags to fit the available space.  I tried doing this using React state, but it looks bad if you can see it adding / removing tags. I think the other approach would be to write a tag “measure” function, or otherwise repeatedly render + size them offscreen, but that’d still force layouts, and in this case the tags are not identical react components (the “4 more” tag is slightly different)

I added a storybook that makes it easy to test what this looks like in a bunch of scenarios.

Sidenote: There’s a bunch of cruft here because the “Target” column components all have to support a “tags” rendering and a “plain” rendering.  This is going away soon when we remove the FF allowing users to revert to the old runs page, and I think it’ll clean up this code!
