fix(vcs): wrap long refs in Git log commit details (#999)

Branch and tag labels in the commit details pane inherited the graph row's 180px single-line limit and were clipped. Labels in the details metadata now use the pane width and wrap, including names without break points; graph-row labels keep their single-line ellipsis.

Fixes #996
