Update API specifications with fern api update

Update API specifications by running fern api update.

Note

Medium Risk
Medium risk because it changes the public OpenAPI contract (new/changed schemas, new endpoint behavior, and pagination params) which can break generated clients and integrations if they rely on previous shapes or response codes.

Overview
Updates openapi.json with a refreshed API contract, adding OAuth-related auditing/session fields (new oauth-consent-* action types and ActionOAuth schemas, UserSession OAuth metadata and OAuthScope, plus performedByClientId).

Expands several schemas and request/response shapes: ADRs now include content; catalog technology status becomes nullable (with semantics for private technologies); diagram export adds maxWidth; model-object expansion adds flows/flowsExpanded; organizations gain aiModel and oauthLandscapeWriteEnabled; share links add adrId, new mode values, and a new PATCH update operation alongside DELETE.

Adds cursor pagination (cursor, limit, nextCursor, x-fern-pagination) to model object/connection list endpoints, broadens the diagram description generation request body to support filtering, and standardizes many endpoints to include 403 Forbidden responses.
