test: exclude pytest.fail() lines from coverage via pyproject

pytest.fail(...) marks a branch that must never execute, so exclude it
globally in coverage.report.exclude_also instead of per-line pragmas. Drops
the # pragma: no cover comments added for the bounded-stream tests, and
strengthens the whitespace-padded-key redaction test to assert the masked
form. Pre-existing pragmas elsewhere are now redundant and can be swept
separately.
