fix(GRO-1213): add missing impersonationAuditLogs mock in waitlist.test.ts

portalAudit middleware calls db.insert(impersonationAuditLogs) on every
portal request. The waitlist test mock was missing this export, causing
insertedValues to be double-counted (once for waitlist entry, once for
audit log).

Added impersonationAuditLogs proxy and separate insertedAuditValues
tracking to isolate audit log inserts from business-logic inserts.
