Run e2e tests against live backend

[phibkro]

Playwright e2e tests exist in apps/dashboard/e2e/ but only run against a local dev server. Several tests are .skipped because they need a running backend with valid credentials.

Tasks

• Set up test user credentials for e2e
• Unskip auth tests that need a backend (auth.spec.ts:32, auth.spec.ts:49)
• Add CI job to run e2e tests (needs backend + dashboard running)
• Consider using Playwright's storageState for authenticated test fixtures

Files

• apps/dashboard/e2e/auth.spec.ts
• apps/dashboard/e2e/password-reset.spec.ts
• apps/dashboard/playwright.config.ts
