Subject: [PATCH] fix(dataEvents): widen event metadata typing beyond string

Event metadata accepts string, number, date, link, rich link, and monetary
amount values (per public docs and server-side handling), but the OpenAPI
schemas restrict it to additionalProperties.type: string, generating metadata
as Record<string, string> in the SDKs. Widen create_data_event_request.metadata
and data_event.metadata to additionalProperties: true in both the stable (2.14)
and preview overrides so generated SDKs type it as Record<string, unknown>.
