Add support for listing Applications and API Keys

Hi WorkOS team 👋 We’re currently [developing an integration module for WorkOS in Cartography](https://github.com/cartography-cncf/cartography/pull/2219), our open-source CSPM (Cloud Security Posture Management) platform. As part of this work, we need read access to organization-level configuration objects, specifically: • Listing Applications • Listing API Keys At the moment, these resources are not exposed in the workos-python SDK, which blocks us from fully modeling the WorkOS control plane in Cartography. Having SDK support for these endpoints would allow us to: • Inventory WorkOS applications and credentials • Build security and visibility mappings between identities, apps, and API keys • Keep Cartography’s WorkOS integration aligned with the actual platform state Thanks in advance!
