* Ensure commit-statuses box is sized correctly in headers

When viewing commits as commits the commit-status box will be fixed at 30px in height
due to being forced to be this size by a fomantic selector. This PR simply adds a
few more selectors to force this to have height auto.

Fix go-gitea#18498
