Account-Rotation: Login/Premium-Badges + Live-Rotations-Panel + "Alle pruefen"

- Pro Mega-Debrid-Account UND Debrid-Link-Key im Bearbeiten-Dialog: Badge mit
  Login-Gueltigkeit + Premium-Restlaufzeit (connectUser vip_end / account/infos premiumLeft)
- "Alle pruefen"-Button oben rechts; prueft alle Accounts (Concurrency-Cap 4),
  Ergebnis persistiert (debridAccountStatuses), ueberlebt Neustart
- Rotations-Verlauf-Panel: zeigt live welcher Account/Key versucht wurde + warum
  gewechselt (Ring-Buffer -> Snapshot -> UI), statt nur "Link-Umwandlung erneut"
- Bug A: Mega-Debrid Per-Account-Verbrauch wurde nie erfasst (Heute/Insgesamt immer 0)
- Bug B: isProviderConfigured erkannte reine megaCredentials-Multi-Config nicht
- Neu: account-check.ts (standalone), CHECK_DEBRID_ACCOUNTS IPC, 13 Tests
