fix: add CSS file recovery mechanism for failed tarball extractions

Browse Source 
Enhanced the CSS verification to actively recover the CSS file if it's
missing, empty, or corrupted after tarball extraction. The script now
attempts direct extraction of just the CSS file from the release tarball
as a fallback mechanism.

This ensures that even if the main tarball extraction has issues, users
will still get a working CSS file and proper frontend styling.
