ci(coverage): Refine and update Codecov workflow

- Adjust workflow to skip coverage steps for Dependabot PRs.
- Refine conditions to upload coverage reports only on 'push' event.
- Update Codecov upload naming to reflect all tests instead of just unittests.
- Change flags to `all` for a more comprehensive report.
