Rebuild and expand E2E tests for Settings flows

- Updated Playwright config to enable 8 workers locally while maintaining single worker on CI.
- Rebuilt Settings Navigation E2E tests to verify page transitions and default redirects.
- Reintroduced Password Change E2E tests to validate form display and interactions.
- Expanded Profile Settings E2E tests to include email read-only verification.
- Marked Sessions Management E2E tests as skipped, pending route implementation confirmation.
