ValuSafe 4.7 – One-click updates

One-click updates. Recommended for all installations - from now on, the next versions can be installed from within ValuSafe.

• Administration > Update shows whether a new version is available, downloads the update package on request, verifies its Ed25519 signature and installs it. The database is backed up first; if the self-test or a migration fails, the previous version is restored.
• Servers without internet access can upload the update package instead.
• Version check: at most once a day, and only when an administrator opens the administration, ValuSafe asks palindrom.de whether a new version exists. Nothing is transmitted except the server's IP address. Switch it off with define('VALUSAFE_UPDATE_PRUEFEN', false); in config.php. The privacy policy template has a new section 10 for it.
• Docker: the image is updated as a whole, not via the button (VALUSAFE_DOCKER=1).

Updating from 4.6.1: copy the new files over the old ones (config.php, upload/, documents/, backups/ stay). No database migration. If you have already adapted datenschutz.php, add section 10 "Version check" from the template yourself.
The button works from the update after 4.7 - 4.7 itself is installed by hand.
