refactor(operator-trend): collapse _side_from_status clones onto _resolve_side

Seventeen reset/reentry/rebuild/restore side classifiers each hand-spelled a
confirmation member set plus its clearance mirror (the same strings with the side
word swapped), cloning identical control flow seventeen ways. Replace them with a
shared _resolve_side(status, *confirmation_members) helper that derives the
clearance mirror once (cached); each classifier is now a one-line delegator.
Proven byte-identical by the restore-tier golden contract + full suite. Second
scalar-primitive slice of the operator_resolution_trend fractal collapse.
