fix(ci): extract host and port from NAS_HOST secret

NAS_HOST can be either 'host' or 'host:port'. The previous workflow
passed the whole value as the SSH target, which fails with
'Could not resolve hostname 192.168.1.21:222' when the port is included.

Parse the secret into NAS_SSH_HOST and NAS_SSH_PORT and pass them
explicitly to ssh.
