Fix agenix-rekey: add real uConsole host key, re-encrypt secrets

- Update uConsole hostPubkey from dummy to real SSH host key
- Add uConsole host key to keys.nix
- Add age.rekey config to lazyworkhorse
- Add SSH host key to identityPaths on both hosts
- Re-encrypt builder_key.age and gortium_password.age for both hosts
