fix: widen settings edit modal and clip TextInput overflow

The settings edit modal had min_w 380px, which was too narrow for
typical filesystem paths and let the TextInput overflow visually.
Pin the modal width at 640px and wrap the input cell with
overflow_hidden + min_w_0 so long values clip cleanly inside the
field instead of bleeding past it.
