Improve issue and MR mobile UI

Improve the mobile UI for issues and merge requests. To make use of Bootstrap's column grid this also slightly alters the current desktop UI. Namely, the state box is slightly wider and is a 2-column width rather than being a fixed width. This makes it so we can easily break the row into 2 lines on mobile.
