Consolidate www workflows: lint → build → e2e → deploy

Merge deploy.yml and e2e-tests.yml into single www-ci.yml workflow:
- Single Node/pnpm setup (was duplicated)
- Runs lint, build, E2E tests in sequence
- Deploy only happens on main AND after E2E tests pass
- Upload playwright report on test failure
