Add coverage reporting to tox environments and fix paver test command

- Add pytest-cov to all tox environments
- Configure all pytest commands to generate coverage reports (term + html)
- Use --cov-append for environments with multiple test runs
- Update paver test command to run tox instead of pytest directly

This fixes the issue where 'paver test' failed due to conflicting framework
dependencies, and enables automatic coverage reporting for all test runs.
