Three gaps on the backoffice customer detail page:
- Rejecting a change request or sending it back for correction notified
nobody. Adds CompanyNotifierService.changeRequestReturned, which pings
the customer desk with the reviewer, the outcome and the note. Marketing
joins that desk via customers:view + customers:get_notification in the
role preset — grants still come from the IAM UI, the preset only sets
the default for new environments.
- submitted_by / reviewed_by / actor_id were stored but never resolved, so
the History tab could say what changed but never who asked or who sent
it back. Resolves them through a shared iam-user-name util (deduped from
the private copy in contract-document-history.service) and renders
"Requested by" / "Sent back to marketing by" lines. The
changes_requested badge is relabelled to match the workflow.
- "View" opened an in-page modal one document at a time. Adds
openFileInNewTab, which opens the tab inside the click gesture and fills
it once the authenticated fetch resolves, and an "Open all" button that
loops over the documents table so every file lands in its own tab.
