Update coverage badge to simple CI link

- Replace Codecov badge with simple coverage badge linking to CI
- Add fail_ci_if_error: false to Codecov upload to prevent CI failures
- Coverage badge now shows "coverage - check CI" and links to CI results
- Codecov can still be enabled later by adding CODECOV_TOKEN secret
