Add API Key and REST API support for user functionalities

[devleejb]

Description:
To support the automation of creating CodePair Document documents for use in Bi-Weekly sessions, we propose the addition of an API Key and REST API support. This would enable users to programmatically manage document creation without manual intervention.

Why:
Implementing API Key and REST API support would streamline the document creation process, improving efficiency for users and enhancing the overall functionality of the system. This is particularly important for scenarios that require frequent document generation as part of regular workflows.
