feat(vcs): show the selected commit's details in the Push dialog

Selecting one outgoing commit in the Push dialog now shows its full message, revision, author and time above its changed files. A Group by Directory toggle switches the files between a directory tree and a flat list (each file with its directory beside the name), and the choice is remembered.

Fixes #1373
