fix(realdebrid): keep background downloads noninteractive

Restrict browser window creation to explicit login actions so account activation, status probes, and download retries never open or reopen Real-Debrid windows. Remove the automatic login polling loop from web unrestrict and return a clear login-required error instead. Cover concurrent fresh fallback instances, manually closed windows, and authenticated fair-use failures without popup creation.
