E2E Tests for Login Flow and Dashboard

Problem/Feature Description

A web application has a login page and an authenticated dashboard. Write Cypress E2E tests covering the login flow and the dashboard page.

The app runs on http://localhost:3000 with these pages:

• /login -- email and password form with "Sign in" button
• /dashboard -- displays a welcome banner, recent activity feed, and quick-action cards
• /dashboard/profile -- user profile page showing name, email, and avatar

The app has these API endpoints:

• POST /api/auth/login -- authenticates user, sets session cookie
• GET /api/dashboard/summary -- returns dashboard summary data
• GET /api/user/profile -- returns current user profile

All dashboard pages require authentication. Unauthenticated users are redirected to /login.

Output Specification

Produce:

• cypress.config.ts -- Cypress configuration
• cypress/e2e/login.cy.ts -- tests for login flow (success, failure, validation)
• cypress/e2e/dashboard.cy.ts -- tests for the authenticated dashboard
• cypress/support/commands.ts -- any reusable test helpers
• package.json -- with cypress dependency listed

You may create additional support files for good test organization.
