- Remove old Excel export implementation (TransmittalsExport)
- Update ExportCompleteJob to use new PDF job instead of Excel
- Add TestQueueJob for queue testing with new route
- Update notification label from "Download File" to "Download PDF File"
- Fix auth() helper usage by importing Auth facade consistently
