Add view and edit controls to translation job screen

Add control at the top of the original post column on translation job screen: `[link]view post[/link]`, `[link]edit post (dependant on cap)[/link]`.

Start by locating the translation job screen and its original post column, then inspect how existing view or edit links and capability checks are handled. Done means the column shows a view post control and an edit post control only when the user has the required capability; no file or test is named in the issue.
