Upgrade Hikube platform from 2026-07-29 21:00 CEST to 2026-07-30 05:00 CEST

This update upgrades core platform components, delivering the latest security patches, improved stability, performance optimisations, and new capabilities. It is rolled out node by node: most VMs are live-migrated with no interruption (you may notice a brief network blip), while those that cannot be live-migrated (e.g. GPU passthrough) will be restarted automatically.
