Bundle G of Audit Log #23 M2. Bridges the FallbackAuditWriter primary- failure counter into the Site Health Monitoring report payload so a sustained audit-write outage surfaces on /monitoring/health instead of disappearing into a NoOp sink. - SiteHealthReport: add SiteAuditWriteFailures (defaulted, additive). - ISiteHealthCollector + SiteHealthCollector: new IncrementSiteAuditWriteFailures() counter, per-interval reset semantics matching ScriptErrorCount / DeadLetterCount. - HealthMetricsAuditWriteFailureCounter: adapter forwarding IAuditWriteFailureCounter.Increment() to the collector. - AddAuditLogHealthMetricsBridge(): swaps the NoOp default registration for the real bridge; called from SiteServiceRegistration after AddSiteHealthMonitoring + AddAuditLog. - Existing host-wiring test updated: site composition now resolves HealthMetricsAuditWriteFailureCounter (not NoOp). Tests: HealthMonitoring 60 -> 63 (3 new), AuditLog 56 -> 59 (3 new), full solution green.
