fix: add data-testid attributes to fix flaky E2E selectors

- Add data-testid="stat-card-wrapped-status" to observability page
- Add data-testid="settings-page-heading" to settings page
- Update E2E tests to use stable data-testid selectors instead of text matching

Fixes strict mode violations where getByText matched multiple elements.
