chore(incident-followup): close 4 tails from 29.05 disk-full incident

ремонт: incident-followup cleanup batch — 4 хвоста

1. Larastan baseline regenerated (was 161 errors pre-existing IDE helper drift)
2. Deptrac Mail: [Model, Service] + ADR-005 amend (was 4 pre-existing violations)
3. PG logrotate config in setup-logrotate.yml
4. F1 6 mismatches — RCA updated (algorithm divergence trigger global vs verify per-tenant)

+3 cspell words: notifempty, missingok, верифицируется.
