List deployments API and browser completion documented

Developers can now retrieve deployment history programmatically and complete paused tasks directly from frontend applications. Documentation has been added for the new list deployments API endpoint, allowing retrieval of environment deployments with pagination and filtering by status or date. Additionally, the waitpoint tokens guide now clarifies how to complete paused tasks directly from the browser using a public access token, taking advantage of newly enabled CORS support. This eliminates the need to proxy token completion requests through a backend server. The documentation updates also include a fix to the configuration file reference and clarifications around the behavior of the latest deployments endpoint in self-hosted versus cloud environments.
