Adds a dedicated ExecutionId column to the Audit Log — one universal per-run
correlation value stamped on every audit row (sync ApiCall/DbWrite, the cached
call lifecycle incl. the S&F retry-loop path, NotifySend, central NotifyDeliver,
inbound). CorrelationId keeps its per-operation lifecycle meaning. Additive
schema (AuditLog.ExecutionId, Notifications.OriginExecutionId); UI column +
filter + drill-in; CLI + ManagementService filter.
