Update API specifications with fern api update

[github-actions]

Update API specifications by running fern api update.

Note

Medium Risk
Medium risk because this updates public OpenAPI contracts (new required fields, new enums, pagination params/response fields, and additional 403 responses) which can break generated clients and integrations if not updated in lockstep.

Overview
Updates the OpenAPI contract with new OAuth/auditing support: adds oauth-consent-grant/oauth-consent-deny action types and ActionOAuth schemas, introduces OAuthScope, and extends UserSession/action records with OAuth context (e.g., clientId, landscapeId, scopes, performedByClientId).

Expands several API surfaces: adds cursor-based pagination (cursor, limit, nextCursor + x-fern-pagination) to model object/connection list endpoints, adds ShareLink updates (new PATCH update operation), and extends share link options with adrs mode plus adrId.

Refines schemas and request shapes: adds ADR content, allows CatalogTechnology.status to be nullable to represent private technologies, adds maxWidth to diagram PNG export options, upgrades diagram AI description generation input to DiagramContentGenerateDescriptionFilter (supports modelObjectIds filtering), adds flows expansion for model objects, introduces org-level aiModel and oauthLandscapeWriteEnabled, tightens import payloads with additionalProperties: false, and broadens many endpoints to explicitly return 403 Forbidden.
