fix(board): --brief's zero-debt branch no longer claims zero pending mail

Found in review of the previous commit, before catalog tags 0.22.0: once
n_owe counts OWED repos rather than raw pending, its ==0 branch could fire
while a repo still held FYI-only mail, making "Ingen repo har uhaandtert
innboks" false at the exact moment it printed. Fixed to state only the
debt claim, and to name any FYI-only mailboxes found instead of letting
their existence go unmentioned. No fixture in the shared test tree ever
reached n_owe==0 (it always carries a debtor), so this needed its own
isolated-root fixture to pin.

Still part of the 0.22.0 release -- amends that changelog entry rather
than bumping again, since no tag exists yet.

board-selftest.sh: 150 -> 152 checks.
