Implement the CRUD operations for the /users/me/blocklist/numbers endpoint to manage the blocklist feature in Wazo. This task involves developing the backend logic to handle Create, Read, Update, and Delete operations on phone numbers for end-users.

Job to be Done:

1. CRUD Operations:

   • POST/PUT Validate the input to ensure the phone number is in the correct format (+E.164)

     • Validation to limit to 1000 numbers per user

   • DELETE Ensure the operation is idempotent and handles cases where the number does not exist.

   • GET Users can see blocked numbers he added

     • Filter to find a matched number

2. Documentation:

   • Update the API documentation to include the new /users/me/blocklist/numbers endpoint.

   • Provide examples of requests and responses for each CRUD operation.

3. Integration Testing

   • Perform integration testing that the blocklist feature works as expected

   • Write a performance test with 30 000 blocked numbers (3000 users with 10 numbers each).
