batches: clean up detail page tabs
Created by: courier-new
This PR does two things:
- Gets rid of usage of
' '
for spacing, replacing it with larger margins (characters can render inconsistently across environments, whereas margin enforces consistency) - Hides the executions count badge when there aren't any active executions (I think this feels a bit more natural than seeing it a 0 most of the time)
Test plan
This screen is covered by storybook stories as well as Chromatic diffing. It should report a diff for exactly what I have changed here.
