Integrate the Create Account API with Invite Codes

[cbell504]

The goal of this ticket is to make sure that when a user must have an invite code when they create an account. This ticket includes the work for both the frontend and the backend.

Frontend

Create a new text for the invite code
Send that new field to the create account endpoint

Backend

Take in that new property in the request
Use the PermissionService to verify that the code exists for the account
Create the account and then remove the code from the DB.
