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
- Cross-browser testing support with Playwright
- Authentication system testing end-to-end

+# p-try [![Build Status](https://travis-ci.org/sindresorhus/p-try.svg?branch=master)](https://travis-ci.org/sindresorhus/p-try)
+
+> Start a promise chain
+
+[How is it useful?](http://cryto.net/~joepie91/blog/2016/05/11/what-is-promise-try-and-why-does-it-matter/)
+
+
+## Install
+
+```
+$ npm install p-try
+```
+
+
+## Usage
+
+```js
+const pTry = require('p-try');
+
+(async () => {
+	try {
+		const value = await pTry(() => {
+			return synchronousFunctionThatMightThrow();
+		});
+		console.log(value);
+	} catch (error) {
+		console.error(error);
+	}
+})();
+```
+
+
+## API
+
+### pTry(fn, ...arguments)
+
+Returns a `Promise` resolved with the value of calling `fn(...arguments)`. If the function throws an error, the returned `Promise` will be rejected with that error.
+
+Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.
+
+#### fn
+
+The function to run to start the promise chain.
+
+#### arguments
+
+Arguments to pass to `fn`.
