test(e2e): add comprehensive auth flow tests

Created Playwright E2E tests for complete authentication flow to
prevent regressions and validate all auth-related fixes.

Test Coverage:
-  Login with valid credentials
-  Login with invalid credentials (error handling)
-  Session persistence after page refresh (P1.2)
-  Logout clears session and redirects
-  Register new user
-  Protected routes redirect when not authenticated
-  Health endpoint accessibility (P1.6)
-  CORS headers present on API requests (P1.1)
-  Token refresh handling
-  Max refresh attempts logout (P1.4)
-  CSRF token on mutations (P1.3)

Test Structure:
- Authentication Flow: 7 tests
- Token Refresh Flow: 2 tests
- CSRF Protection: 1 test

Usage:
  npx playwright test tests/e2e/auth.spec.ts

Impact: Automated regression detection for all Phase 1 auth fixes.

Fixes: P3.3 from audit AUDIT_TEMP_29_01_2026.md
