Add E2E tests with workflow execution support

Implements comprehensive E2E testing framework for foundry-sample-functions-python
with workflow execution capabilities.

Features:
- Workflow execution via Fusion SOAR UI
- Navigation through hamburger menu to workflows
- Execute workflows with optional input parameters
- Verify workflow execution completion
- Support for workflows requiring inputs (host-details)
- Separate rendering vs execution (ServiceNow workflow)

Test Coverage:
- ✅ Test hello function workflow - Executed successfully
- ✅ Test log-event function workflow - Executed successfully
- ✅ Test servicenow function workflow - Render only (dummy credentials)
- ⏭️ Hello UI extension - Skipped (tab structure needs investigation)
- ⏭️ Test host-details function - Skipped (host ID implementation needed)

New Components:
- WorkflowsPage: Full workflow execution methods
- HostManagementPage: For retrieving host IDs (ready for future use)
- HelloExtensionPage: Socket-based extension testing
- Updated test suite with serial execution

Configuration:
- List reporter (no browser popup)
- App installation/uninstallation setup/teardown
- Environment-based configuration

Results: 6 tests passed, 2 skipped in ~45s

+# Foundry E2E Tests
+
+End-to-end tests for the foundry-sample-category-blocking application using Playwright.
+
+## Prerequisites
+
+1. **Environment Setup**: Create a `.env` file with your Falcon credentials:
+   ```bash
+   FALCON_USERNAME=your.email@company.com
+   FALCON_PASSWORD=your-password
+   FALCON_AUTH_SECRET=your-totp-secret
+   FALCON_BASE_URL=https://falcon.us-2.crowdstrike.com
+   APP_NAME=foundry-sample-category-blocking
+   ```
+
+2. **App Deployment**: Ensure the app is deployed to your Falcon environment:
+   ```bash
+   foundry apps deploy
+   foundry apps release
+   ```
+
+## Running Tests
+
+### Basic Test Execution
+```bash
+# Run all tests
+npm test
+
+# Run with list reporter (cleaner output)
+npm test -- --reporter=list
+```
+
+### Debug Modes
+
+#### 1. Verbose Logging Mode
+Shows detailed debug information including element states, wait conditions, and context:
+```bash
+npm run test:verbose
+```
+
+#### 2. Playwright Debug Mode  
+Opens browser in debug mode with step-by-step controls:
+```bash
+npm run test:debug
+```
+
+#### 3. Manual Debug Environment
+Set debug flag manually:
+```bash
+DEBUG=true npm test
+```
+
+#### 4. UI Mode
+Interactive test runner with visual debugging:
+```bash
+npm run test:ui
+```
+
+### Debug Mode Features
+
+When debug mode is enabled (`DEBUG=true`), you'll see:
+- **Element Wait Details**: Timeout values, element states, retry attempts
+- **Screenshot Context**: Detailed information about captured screenshots  
+- **Navigation Context**: Page timing and URL patterns
+- **Interaction Context**: Click attempts, element visibility checks
+- **Error Context**: Enhanced error messages with debugging information
+
+### Common Debug Scenarios
+
+#### App Not Found
+If tests fail with "App not found":
+1. Verify app deployment: `foundry apps list-deployments`
+2. Check APP_NAME matches deployed app name
+3. Run with debug mode to see navigation attempts
+
+#### Element Interaction Failures
+If clicks timeout or fail:
+1. Use `npm run test:debug` to step through interactions
+2. Check for element interception issues in debug logs
+3. Verify iframe loading and content accessibility
+
+#### Authentication Issues
+If login fails:
+1. Verify `.env` credentials are correct
+2. Check TOTP secret is current and valid
+3. Run single test with debug mode to isolate issue
+
+## Test Structure
+
+- **authenticate.setup.ts**: Handles Falcon login with MFA
+- **foundry.spec.ts**: Main test suite with app installation and interaction tests
+- **Page Objects**: Structured page interactions in `src/pages/`
+- **Configuration**: Environment-specific settings in `src/config/TestConfig.ts`
+
+## Available Test Commands
+
+| Command | Description |
+|---------|-------------|
+| `npm test` | Run all tests with default settings |
+| `npm run test:verbose` | Run with debug logging enabled |
+| `npm run test:debug` | Run in Playwright debug mode |
+| `npm run test:ui` | Run with interactive UI mode |
+
+## Troubleshooting
+
+- **Tests hang**: Check for modal dialogs or authentication prompts
+- **Navigation failures**: Verify app is installed and accessible in Custom Apps menu  
+- **Element not found**: Use debug mode to inspect page structure and timing
+- **Timeout errors**: Check network conditions and increase timeouts if needed
+
+For more debugging tips, see the test logs and enable verbose mode for detailed information.
