Update API specifications by running fern api update.

Note

Medium Risk
This is a broad OpenAPI surface-area update that adds/changes request/response shapes (pagination, new fields, nullable enums) and new endpoints/status codes, which can break generated SDKs and existing API clients if they assume the old contract.

Overview
Updates the OpenAPI spec to include OAuth auditing and session support, adding new oauth-consent-* action types/schemas, performedByClientId on actions, OAuthScope, and OAuth session fields (clientId, landscapeId, scopes), plus org-level controls like oauthLandscapeWriteEnabled and an aiModel enum.

Introduces cursor pagination for model object/connection list endpoints via cursor/limit, a nextCursor response field, and x-fern-pagination metadata; many endpoints now also explicitly document 403 Forbidden responses.

Refines several schemas and operations: ADRs now include content, catalog technology status becomes nullable (for private tech), diagram export adds maxWidth, share links add adrId and new modes, diagram description generation accepts a filter object, import payload schemas disallow unknown fields (additionalProperties: false), and share links gain a distinct PATCH update operation (with resetShortId) alongside DELETE.
