/**
 * E2E Tests: Shift Sign-Up and Cancellation Flow
 * 
 * These tests verify the complete shift sign-up workflow including:
 * - Shift creation by Manager role
 * - Sign-up and cancellation flow
 * - Capacity enforcement (full shift blocks sign-up)
 * - Past shift validation (no sign-up for past shifts)
 * - Visual capacity indicators (progress bar, spot counts)
