/**
 * Post-review follow-ups.
 *
 *  1. No-address match winner reconciliation: setUserPayoutAddress converts a claimable
 *     'needs_review' match payout (reason 'match_winner_no_address') into a sendable 'pending'
 *     payout once a real address is set, and NEVER touches other 'needs_review' rows (e.g. the
 *     ambiguous single-payout rows, which would double-pay if reset).
 *  2. Match boot-recovery age guard: _recoverAbandonedMatches reclaims all in-flight matches
 *     immediately in single-instance mode, but only aged-out ones when MATCH_SINGLE_INSTANCE=false.
