Overview:

In a consortium environment, MARC authority records can be either shared across tenants within the consortium or local to each tenant. Report generation in mod-data-export-worker currently does not distinguish between shared and local records or reflect this distinction in export output. To improve clarity for users, reports such as "Failed updates: linked bibliographic fields" and "MARC authority headings update" should include appropriate columns ("Instance record type" and "Authority record type") with the values "Shared" or "Local", depending on the record type. For non-consortium environments, these columns should not appear in the reports.
This story builds on the solution implemented in mod-entities-links, leveraging the newly extended statistics model with the source field (shared or local) for seamless integration within mod-data-export-worker.

Requirements:

• Extend report generation logic in mod-data-export-worker to include record type columns in the output for consortium environments.

• Ensure the source field (shared or local) in the statistics model is accurately reflected in the reports.

• Prevent inclusion of unnecessary columns when the tenant is NOT in a consortium environment.
