fix🐛: format the dept-list error instead of printing its verb

log.Error is the unformatted entry point, so "find dept list error, %s"
went out with the %s intact and the error text glued to it:

    find dept list error, %sconnection refused

Errorf is what the line meant. go vet reports this once go-admin-core's
logger is recognised as a print-style wrapper, which it is from v2.10.0.
