fix(gui): let the Sync page use the full width

The transfer label did not ellipsize, so a long file name set the
column's minimum width and pushed it past the clamp. The page width
changed with every file.

The label now ellipsizes in the middle, and the Sync page drops the
clamp so Overview and Folders fill the space next to the sidebar.
