2025-10-29 Guix Moe build farm head node migration

Head node of the build farm has been migrated to a new machine nuporta.
CPU: Intel Xeon E3-1275v5 (4C8T, Q4 2015) -> AMD Ryzen 7 3700X (8C16T, Q3 2019)
RAM: 64GB DDR4 ECC
Disks: 2x 4TB HDD -> 2x 8TB HDD
Config: https://codeberg.org/hako/Testament/src/branch/trunk/config/nuporta.org

Specs of nuporta is more suitable for build tasks and long term operation. It can also be upgraded on RAM and SSD in the future.

I forgot to migrate Guix signing key and the old key is no longer available. A new signing key is used additionally for new substitutes, see Usage for setup.

(public-key (ecc (curve Ed25519) (q #552F670D5005D7EB6ACF05284A1066E52156B51D75DE3EBD3030CD046675D543#)))

nuporta is located in Finland, replacing the original cache-fi mirror. Since there's no machine in Germany any more, cache-de mirror has been made as an alias to cache-fi and cache-cdn is placed on the new head node.
