Initial Scaffold for FastAPI Implementation

[lasryariel]

• Parent Issue: #771

Overview

This issue involves creating the foundational scaffold for our FastAPI implementation. The primary goal is to establish a starting point for the migration, focusing on user authentication (sign-in/sign-up) and ensuring early integration with the client interface. The new API should be testable from the client once the basic setup is complete.

Action Items

• [x] Create a "trunk-type" branch named "fastapi-migration" branch in /api-v2 to manage the development of FastAPI migration.
• [x] Set up a new folder structure and add a basic scaffold for the FastAPI application.
• [x] Create updated readme
• [x] Implement basic authentication endpoints:
  • [x] User Sign-In
  • [ ] User Sign-Up
• [ ] Integrate the initial scaffold with the client to validate the API setup.
• [ ] Review the scaffold and implementation progress with the team.
