Converts a JWT (JSON Web Token) to an API token.

JWTs are commonly used for authentication in web applications. They contain encoded information about the user and are typically short-lived for security reasons.

This endpoint exists to allow clients who have authenticated via JWT (e.g., through Supabase) to obtain a long-lived API token. The API token can then be used for subsequent requests to the API without requiring frequent re-authentication.

This conversion process enhances security by separating the authentication mechanism (JWT) from the API access mechanism (API token), while providing a seamless experience for users transitioning from web-based authentication to API usage.
