Update API specifications with fern api update

[github-actions]

Update API specifications by running fern api update.

---

Note

Medium Risk
Medium risk because it changes public API contracts (new action types/fields, new PATCH operation, stricter additionalProperties: false) which can break existing clients and generated SDKs if they relied on previous shapes or error codes.

Overview
Updates the OpenAPI contract to include OAuth consent activity tracking by adding oauth-consent-grant/oauth-consent-deny action types and new ActionOAuth* schemas, plus a new performedByClientId field on action records.

Extends session and content payloads by adding clientId/landscapeId to UserSession (OAuth sessions) and adding markdown content to ADR schemas.

Tightens and expands API behavior by adding 403 Forbidden responses across many endpoints, introducing a PATCH shareLinkUpdate operation (with optional resetShortId) while making shareLinkDelete a true DELETE, and setting multiple import-related schemas to additionalProperties: false (stricter validation), including an updated ModelObjectImport.parentId hierarchy description.
