Encodes the string just once for compare json

Without explicit directory entries, some zip viewers (simpler tools,
web-based viewers) don't show the folder structure when browsing the
archive. Add a _ensure_zip_dirs() helper that writes directory markers
for all parent paths of each file entry, deduplicating via a set.
Uses ZipFile.mkdir() (available since Python 3.11, the project minimum).

+
+Upgrading to Paperless-ngx v3 can only be performed from version 2.20.15. If you are running an older version, please upgrade to v2.20.15 before proceeding with the v3 upgrade.
