Update API specifications with fern api update

[github-actions]

Update API specifications by running fern api update.

---

Note

Medium Risk
Moderate risk because this updates public API contracts (new auth requirements, new/changed schemas, pagination parameters, and additional error responses) which can impact generated SDKs and existing clients.

Overview
Adds OAuth-related audit/action coverage to the spec (new oauth-consent-* action types and ActionOAuth schemas), plus OAuth session fields (clientId, landscapeId, scopes) and performedByClientId on actions.

Expands multiple schemas and capabilities: ADRs now include content; organizations add aiModel, oauthLandscapeWriteEnabled (required), and billingMonthlyCost; model-object expansion adds flow support (flows/flowsExpanded); share links add adrId and new modes (model-viewer, adrs).

Introduces API behavior changes including cursor pagination for model object/connection listing (cursor, limit, nextCursor + x-fern-pagination), a ShareLink PATCH update operation (with optional resetShortId), diagram export maxWidth, diagram description generation filtering (modelObjectIds), catalog technology status becoming nullable for privacy, import schemas disallowing unknown fields (additionalProperties:false), GET /catalog/suggestion/brand requiring auth, and broad addition of 403 Forbidden responses across many endpoints.
