[github-actions]

Update API specifications by running fern api update.

Note

Medium Risk
Medium risk because this is a broad OpenAPI contract update (new endpoints/fields and tighter schema validation) that can break generated clients or request payload compatibility if consumers relied on the previous shapes.

Overview
Updates the OpenAPI spec to cover OAuth consent auditing by adding new action types (oauth-consent-grant/oauth-consent-deny), related ActionOAuth* schemas, and a new performedByClientId field on actions.

Expands session and ADR payloads with OAuth/session metadata (UserSession.clientId/landscapeId) and adds ADR content (markdown) to ADR, ADRPartial, and ADRRequired.

Tightens import request schemas by setting additionalProperties: false on multiple *Import objects and adjusts ModelObjectImport.parentId hierarchy rules; also adds documented 403 Forbidden responses to many endpoints and introduces a PATCH Update operation for Share Links (with optional resetShortId) alongside the existing DELETE.
