[tests] Add PHPUnit output options (#84)

[coisa]

Summary

• Add tests command options for PHPUnit progress suppression and concise coverage text output.
• Forward --no-progress to PHPUnit only when requested, and forward --only-summary-for-coverage-text behind the DevTools --coverage-summary option.
• Update reports to delegate tests with --no-progress and --coverage-summary, and document the new CLI behavior.

Testing

• composer dev-tools tests -- --filter='TestsCommandTest|ReportsCommandTest'
• composer dev-tools code-style
• composer dev-tools tests
• composer dev-tools docs
• git diff --check
