Subscription Management System (Requirements)

You are tasked with building a subscription management system that allows users to subscribe to a service and manage their subscription status. The system will consist of a REST API backend and a simple frontend built using Vue.js.

Backend

The backend should be built using PHP 8 and Symfony 5.4 (or higher) and should expose the following API endpoints:

Authentication

• POST /api/auth/login: Authenticate a user and retrieve an access token.
• POST /api/auth/register: Register a new user.

Subscriptions

• GET /api/subscriptions: Get a list of all the available subscriptions.
• GET /api/subscriptions/{subscription_id}: Get a single subscription by ID.
• POST /api/subscriptions/{subscription_id}/subscribe: Subscribe to a subscription. Subscribing to a subscription cancels an already existing subscription.
• POST /api/subscriptions/{subscription_id}/unsubscribe: Unsubscribe from a subscription.
• GET /api/subscriptions/me: Get the current user's subscriptions.

Payment

• POST /api/payment: Make a payment to subscribe to a subscription.

The API should use Doctrine to interact with a MySQL database. The database should have the following schema:

users
- id: int
- name: string
- email: string
- password: string

subscriptions
- id: int
- name: string
- description: string
- price: float
- duration: int

user_subscriptions
- user_id: int
- subscription_id: int
- status: string
- start_date: datetime
- end_date: datetime

The API should follow REST principles and should return JSON responses.
