Set up comprehensive frontend testing infrastructure

- Install Jest for unit testing with React Testing Library
- Install Playwright for end-to-end testing
- Configure Jest with proper TypeScript support and module mapping
- Create test setup files and utilities for both unit and e2e tests

Components:
* Jest configuration with coverage thresholds
* Playwright configuration with browser automation
* Unit tests for LoginForm, AuthContext, and useSocketIO hook
* E2E tests for authentication, dashboard, and agents workflows
* GitHub Actions workflow for automated testing
* Mock data and API utilities for consistent testing
* Test documentation with best practices

Testing features:
- Unit tests with 70% coverage threshold
- E2E tests with API mocking and user journey testing
- CI/CD integration for automated test runs

+# identity-obj-proxy [![Build Status](https://img.shields.io/travis/keyanzhang/identity-obj-proxy.svg?style=flat-square)](https://travis-ci.org/keyanzhang/identity-obj-proxy) [![npm version](https://img.shields.io/npm/v/identity-obj-proxy.svg?style=flat-square)](https://www.npmjs.com/package/identity-obj-proxy) [![test coverage](https://img.shields.io/coveralls/keyanzhang/identity-obj-proxy/master.svg?style=flat-square)](https://coveralls.io/github/keyanzhang/identity-obj-proxy?branch=master)
+An identity object using ES6 proxies. Useful for testing trivial webpack imports. For instance, you can tell Jest to mock this object as imported [CSS modules](https://github.com/css-modules/css-modules); then all your `className` lookups on the imported `styles` object will be returned as-is.
+
+```
+npm install identity-obj-proxy
+```
+
+## Requirement
+No flag is required for Node.js `v6.*`; use `node --harmony_proxies` flag for `v5.*` and `v4.*`.
+
+## Example
+``` javascript
+import idObj from 'identity-obj-proxy';
+console.log(idObj.foo); // 'foo'
+console.log(idObj.bar); // 'bar'
+console.log(idObj[1]); // '1'
+```
