fix(settings): truncate long Agent CLI paths in AI cards

The settings content column is a row flex item, so a long CLI path
set its min-content width and pushed the pane past the window. Let
that column shrink, and ellipsize the path on each managed agent card
while keeping the version visible.

Fixes #3923
