🤖 Augment PR Summary

Summary: Prepares the Netatalk v4.4.3 release by updating versioning, changelogs, translations, and security advisory listings.

Changes:

• Added a new “Changes in 4.4.3” section to NEWS.md with the release highlights and referenced CVE fixes.
• Expanded SECURITY.md to include newly disclosed advisories and their affected/fixed version ranges.
• Bumped the Meson project version from 4.4.2 to 4.4.3.
• Refreshed Japanese documentation translations (PO files) to match updated manual/manpage content.
• Hardened Spotlight-related shell argument quoting by guarding against a NULL input pointer.

Technical Notes: The Spotlight change updates quote_shell_arg() to avoid NULL dereferences, and the doc updates align release notes/security metadata with the v4.4.3 maintenance release.
