Update API specifications with fern api update

[github-actions]

Update API specifications by running fern api update.

---

Note

Medium Risk
Changes the public OpenAPI contract by adding new schemas/fields and new error responses, which can break generated clients and server handlers if not implemented consistently.

Overview
Updates openapi.json to extend audit/action coverage for OAuth consent by adding new action types (oauth-consent-grant/oauth-consent-deny) and corresponding ActionOAuth* schemas, plus a performedByClientId field on action records.

Expands auth/session and content models by adding clientId/landscapeId to UserSession and adding content to ADR schemas.

Tightens and clarifies API contracts by setting additionalProperties: false on multiple import payload schemas, adjusting ModelObjectImport.parentId hierarchy rules (allowing group nesting), adding 403 Forbidden responses across many endpoints, and restructuring the Share Link routes so PATCH is shareLinkUpdate and DELETE is shareLinkDelete (with resetShortId remaining on update).
