fix(ui): improve milestone/project header consistency (#7174)

The related CSS `milestone-card` is used in 3 places:
* global milestone view `/milestones`
* per-repo milestone view
* per-user/org projects view

The first two had gaps too small basically provided by whitespace. The latter was using an unusually large gap via tailwind.
