Rename agent_api_rest crate to agent_api_http

[nanderstabel]

Description

Our current module is named agent_api_rest, which suggests adherence to RESTful API principles. However, since our application follows a CQRS (Command Query Responsibility Segregation) architecture, we do not strictly adhere to RESTful design patterns.

To better reflect our architecture and avoid confusion, we need to rename the module to agent_api_http.

Motivation

Reduces confusion about the API's design principles among team members and new contributors.
