/**
 * Projects Overview Dashboard End-to-End Test
 *
 * Tests the multi-project overview dashboard that shows status across all projects.
 * This verifies that:
 * 1. The overview view can be accessed via the sidebar
 * 2. The overview displays aggregate statistics
 * 3. Navigation back to dashboard works correctly
 * 4. The UI responds to API data correctly
