Bug description

When a public share of a file/folder has a label attached and the screen is narrow enough, it can overlap the actions menu and make it impossible to change the link via web frontend anymore (without hacks like browser window resizing).

Steps to reproduce

1. Open files app and share a file via (externa) link
2. Add a (lengthy) label to the share
3. Save the share and open the share settings again (if closed)
4. Make the screen (body) narrow enough by resizing window

Expected behavior

The action buttons are always visible and the label is abbreviated/ellipsised

Additional info

Tested on 27.1

Start by reproducing the issue in the Files app's public-share settings UI using a long label and a narrow window. Inspect the share actions and label layout entry points, then verify that action buttons remain visible and the label is abbreviated or ellipsised at narrow widths.
