Restore Knowledge Base

Un-archive a soft-deleted knowledge base along with its documents and connectors. Idempotent: a knowledge base that is already active is returned unchanged with no audit entry recorded. Restoring into an archived workspace is a 409, and a knowledge base whose folder is still archived is returned to the workspace root. A workspace folder tree over 10,000 folders is a 413.

POST/api/v2/knowledge/{knowledgeBaseId}/restore
X-API-Key<token>
