Implement M3: expiration threshold alerting with dedup and status transitions

- Add alert_thresholds_days JSONB column to renewal_policies (default [30,14,7,0])
- Add RenewalPolicy.AlertThresholdsDays field + EffectiveAlertThresholds() helper
- Add RenewalPolicyRepository interface + postgres implementation
- Rewrite CheckExpiringCertificates with per-policy threshold alerting
- Add SendThresholdAlert + HasThresholdNotification for deduplication via [threshold:N] tags
- Add Type and MessageLike filters to NotificationFilter + postgres query support
- Auto-transition certs to Expiring (>0 days) or Expired (<=0 days) status
- Record expiration_alert_sent audit events per threshold crossing
- Fix .gitignore: allow SQL migration files, scope server/agent build artifact rules
- Track previously untracked cmd/ and migrations/ directories
- Update docs (README, architecture, demo-advanced) for threshold alerting
