PowerFolder 27.3: folders as network drives, Argon2id, OpenDocument

You can now publish PowerFolder folders as an SMB/Samba/CIFS share, with the existing PowerFolder permissions still applying. Passwords are hashed with Argon2id by default, and existing SHA-256 hashes migrate automatically at the next successful login. The online editor creates new documents as ODT, ODS or ODP; the News page has become an activity feed with bulk restore for deleted files, and a global file search now spans every top-level folder.
