Login Flow Test needs local dev server

[akaihola]

Summary

The login flow test example in SKILL.md requires a local dev server with /login and /dashboard routes to be fully testable.

Example Code

page.goto(f'{TARGET_URL}/login')
page.fill('input[name=email]', 'test@example.com')
page.fill('input[name=password]', 'password123')
page.click('button[type=submit]')
page.wait_for_url('**/dashboard')

Acceptance Criteria

• Create a test login page with email/password fields
• Create a test dashboard page
• Update test to use local test server
• Verify login flow works end-to-end

Context

From SKILL.md example: Test Login Flow section. Currently only testable with external services that have login pages.
