Rotation: jeden Account-Versuch ins ITEM-Log schreiben (Sichtbarkeit)

User sah im Item-Log nur "Link-Umwandlung gestartet" -> "Unrestrict Timeout
60s" -> "erneut Versuch 1/inf", aber nie welcher Account/Key wann probiert
wurde. Die Rotation lief nur in account-rotation.log + Panel.

Jetzt: AsyncLocalStorage-Item-Sink (parallel-sicher bei 8 gleichzeitigen
Unrestricts) leitet JEDEN Rotations-Event in das Log des betroffenen Items:
"Account-Rotation: Mega-Debrid Web - Account 1 (xy) wird versucht / fehl-
geschlagen (Timeout) -> Account 2". Damit ist im Item-Log direkt sichtbar,
ob acc2/acc3 ueberhaupt erreicht werden -> dient auch als Diagnose fuer den
vermuteten Timeout-Bug (kommt separat, falls das Log Stillstand zeigt).
