refactor(AddReportBehavior): update to add history record.

- Introduced PDFBurnerParams configuration for concurrency limit.
- Added SemaphoreSlim to handle concurrent PDF burning for envelopes.
- Updated job to call _mediator.BurnPdf for each envelope with error handling.
- Preserved logging of job execution and envelope UUIDs.
