TransportSettingsTests: default airDrop, set/get round-trip, garbage stored
value falls back to airDrop, oneDriveFolder store/reset, effectiveFolders for
both transports, oneDriveFolderUnavailable's errorDescription contains the path.
OneDriveLocatorTests: fake home tree under Library/CloudStorage — syncRoots
returns only real OneDrive-* directories (ignores a same-named plain file and
a GoogleDrive-* one), MMD-named root sorts first; no CloudStorage dir means
empty roots and a nil defaultRedlineFolder; resolveOneDriveFolder prefers an
existing stored override and falls back to the default when the stored path
no longer exists. All against temp dirs, never the real home.
ReturnWatcherTests: recordUncommended defaults to true and still records an
unmarked PDF (existing AirDrop tests are unaffected); with it set false, an
unmarked PDF is neither recorded nor returned by scanNow, and marking it up
in place with a real PDFKit ink annotation then re-scanning does record it.
