Files no longer go into a shared test space with a guessed folder name.
Instead, resolve each user's personal drive id via GET /graph/v1.0/me/drives
(Basic Auth, same App Token as uploads) on every run, and upload into
Out/год/месяц/день/номер_запуска inside that drive, creating the path via
MKCOL since a fresh personal drive won't have it yet.
Removes the now-obsolete OPENCLOUD_SPACE_ID / resolve_opencloud_user_folder
and the shared-space smoke script.
