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

+# Jest
+
+🃏 Delightful JavaScript Testing
+
+- **👩🏻‍💻 Developer Ready**: Complete and ready to set-up JavaScript testing solution. Works out of the box for any React project.
+
+- **🏃🏽 Instant Feedback**: Failed tests run first. Fast interactive mode can switch between running all tests or only test files related to changed files.
+
+- **📸 Snapshot Testing**: Jest can [capture snapshots](https://jestjs.io/docs/snapshot-testing) of React trees or other serializable values to simplify UI testing.
