Move items within public file system

Moves items to a new location within the public file system. Paths are relative to `public/{publicId}`. Items already in the destination folder are skipped (`count` may be 0). Requires `canMovePublicFileSystemItems`; the token must belong to `projectId`. Does NOT check token expiration.
