fix: keep text-badge fraction statement-only for text reports

The branch-aware fraction assumed `brpart` is the count of missing
branches, which is only true for XML totals. Text reports expose
coverage.py's `BrPart` (partial branches), so gate the branch math on
the XML path to avoid overstating covered branches.
