Pull request overview

Adds a new borrower workflow step (update-metadata) so patron-request bibliographic metadata can be refreshed via the configured catalog lookup adapter after validation, and before sending the request onward. This moves metadata-update behavior out of request creation and into the state model/action pipeline.

Changes:

• Extend the borrower state model with update-metadata (auto) and a new METADATA_UPDATED state between VALIDATED and send-request.
• Implement update-metadata in PatronRequestActionService, including optional “decisionDetails” event custom data about what changed and why.
• Remove metadata-update-on-create from the patron request API handler and update wiring/tests accordingly.
