Update WarehouseCredential

Represents credentials for connecting to Benchling's data warehouse, enabling users to query data using SQL tools like database clients or BI platforms. This includes all warehouse login types: user-generated Direct Access credentials, as well as temporary Insights and Agent credentials. Each WarehouseCredential is tied to a specific Benchling user whose permissions determine what data is accessible through those credentials. Credentials can have an optional expiresAt date for time-limited access and can be permanently disabled via the revoked flag. Once revoked, credentials cannot be reactivated. Users can create multiple credentials (up to a per-user limit) with different label values to distinguish between uses.
