oxide system hardware switch-port status should return a formatted mac address instead of a byte array

In the current output, the mac address shows up as a byte array in decimal:

    ]
  }
}

This should be displayed as a formatted string, like it is in oxide system hardware switch-port show-status:

‣ ./oxide --profile colo-admin system hardware switch-port show-status | grep 'qsfp[89]'
qsfp8   true        true     a8:40:25:05:15:43  false    RS    up/LinkUp       Optical  Speed100G
qsfp9   false       -        -                  -        -     -               -        -
qsfp8   true        true     a8:40:25:05:0f:43  false    RS    up/LinkUp       Optical  Speed100G        <<<<<<
qsfp9   false       -        -                  -        -     -               -        -

Reproduce the system hardware switch-port status command shown in the issue and compare its link.address output with system hardware switch-port show-status. Trace the two CLI output paths to find where the address is serialized, then verify that status displays the MAC as a colon-separated string such as a8:40:25:05:15:43 rather than a decimal byte array.
