Splits test_screen_lock_coverage_part2 via a shared _unlock_helpers.setup_unlock
factory rather than duplicating the fixture, and finishes the remaining
runnerup/manual-workout/status-view test modules under the 250-line cap.
Also splits the pylint hook in two. protected-access, unused-argument and
duplicate-code are how pytest and unit-testing private mixins work, not
defects, and a commit made entirely of test files could never clear the 8.0
batch score with them counted. Source keeps the full rule set — verified that
an injected protected-access is still reported there.
