/**
 * Feature Manual Review Flow E2E Test
 *
 * Happy path: Manually verify a feature in the waiting_approval column
 *
 * This test verifies that:
 * 1. A feature in waiting_approval column shows the mark as verified button
 * 2. Clicking mark as verified moves the feature to the verified column
 *
 * Note: For waiting_approval features, the button is "mark-as-verified-{id}" not "manual-verify-{id}"
