fix(vcs): let Commit and Shelf tree names use the whole row width

File and folder names in the Commit tool window's changes tree (and the Shelf tree, which shares the styles) were capped at 75% of the row, so a long folder name was cut with an ellipsis while a quarter of the row stayed empty, and the gap grew as the window widened. The name now takes the whole row; when it does not fit, the grey detail after it (the path or file count) is truncated first. Stash rows keep their previous shrinking.

Fixes #1367
