Use the openapi typescript client instead of api.ts

[jeroenrinzema]

Problem Statement

Currently we have the API client defined in api.ts which has served it's purpose so far. We would like to rely on a generated client based on the OpenAPI specs ensuring that the integration between the front-end and back end are handled in a more structured manner.

Proposed Solution

We currently have a OpenAPI spec for the backend API. The OpenAPI client included in #155 could be used to interact with the back-end.

Technical Implementation

• Refactor the existing implementation from api.ts to the newly generated OpenAPI client
