feat: add Codecov integration and update badges

- Update GitHub Actions workflow to generate coverage reports
- Add Xdebug coverage for all three database jobs (MySQL, PostgreSQL, SQLite)
- Add Codecov upload steps for each job
- Create .codecov.yml configuration with 75% coverage target
- Update README badges: rename CI to Tests, add Coverage badge
- Add coverage files to .gitignore
