Overview

This PR creates a ServicesContext which is able to provide instances of service classes to child components via a dependency injection container. Additionally, it defines an AbstractUserService class and a partial implementation of this class--LocalUserService--for other developers to complete, and updates the User model to more accurately reflect the player stories regarding contributing to challengers. (see https://www.figma.com/file/0Q2tpQqi9sYcIA3ZyiX3PF/8BY8_POD_Jul30 - Mocks, December Version, US3 - US7).

Test Plan

Unit tests have been implemented for the ServicesContextProvider and the servicesContainer. The LocalUserService is currently added to the coveragePathIgnorePatterns array in jest.config.mjs and must be removed from this array once it is fully implemented. In order to test the ServicesContextProvider, getProvidedContextValue() was added to testing-utils.

Follow ups

The LocalUserService class must be implemented and tested. Once this is implemented, UserContextProvider should also be tested.
