Add comprehensive frontend integration tests with Wallaby

This commit implements browser-based integration testing for the Phoenix LiveView
application using Wallaby and ChromeDriver to test the complete user experience
including JavaScript interactions.

## Changes Made

### Testing Infrastructure
- Add Wallaby dependency for browser automation testing
- Configure Chrome driver with headless mode for CI/CD
- Set up Phoenix server integration for test environment
- Enable screenshot capture on test failures

### Integration Tests
- `test/integration/simple_integration_test.exs` - Basic homepage functionality
- `test/integration/map_integration_test.exs` - Map interface and routing tests
- Tests validate page loading, content rendering, and navigation

### CI/CD Integration
- Update GitHub Actions workflow to install ChromeDriver
- Add separate integration test step in CI pipeline
- Configure headless Chrome for automated testing

### Configuration Updates
- Enable Phoenix server in test environment for Wallaby
- Configure Wallaby with proper base URL and screenshot settings
- Initialize Wallaby application in test helper

## Features Tested
- ✅ Homepage loads with APRS content
- ✅ Main page structure renders correctly
- ✅ Route navigation functions properly
- ✅ Basic Phoenix LiveView functionality

## Next Steps
This provides a solid foundation for expanding to test:
- Interactive map controls and JavaScript functionality
- Real-time packet updates via LiveView PubSub
- User authentication flows and form submissions
- Mobile responsive behavior
