BLOCKER fix, Core half: adds TransportSettings.resolvedAppSupportPaths(),
the transport-aware equivalent of the AirDrop-only
FolderSettings.resolvedAppSupportPaths() — launch code must use this one so
the ReturnWatcher it feeds is never seeded with a stale AirDrop folder while
OneDrive is the persisted transport. Both now share a single
AppSupportPaths.standardRoot() helper for the ~/Library/Application
Support/Shotdeck root, instead of computing it three separate times.
MAJOR fix, Core half: adds OneDriveLocator.isWritableDirectory(at:) — exists
+ isDirectory is not enough; an existing-but-unwritable folder (permissions
revoked) must be treated as unavailable, not silently attempted and surfaced
as a generic PDF-composition failure.
