getAttendeePackageRowsRaw(attendeeId: number,packageGroupId: number,): Promise<Attendee[]>
One attendee's raw booking rows within one package group (real lines only — quantity > 0). Lets a listing-scoped action rehydrate the WHOLE package the selected line belongs to, so a per-member notification resend doesn't treat a single member row as the complete package.
