Feature: Mega-Debrid-Account beim Hinzufuegen sofort pruefen (Gueltigkeit + Premium)

Beim "Hinzufuegen" eines Mega-Debrid-Accounts im Bearbeiten-Dialog wird der Account
jetzt sofort einzeln geprueft (connectUser) — Login-Gueltigkeit + Premium-Restlaufzeit
erscheinen direkt als Badge, ohne den Tab schliessen und "Alle pruefen" klicken zu
muessen. Waehrend der Pruefung zeigt das Badge "Pruefe…".

Neue Einzel-Check-IPC (Spiegel von checkDebridAccounts): CHECK_MEGA_DEBRID_ACCOUNT
-> app-controller.checkSingleMegaDebridAccount(login, password) baut den Account-Entry
(id via getMegaDebridAccountId), ruft die bestehende checkMegaDebridAccount() und merged
das Ergebnis via applyDebridAccountStatuses -> Snapshot -> Badge (gleicher Pfad wie
"Alle pruefen"). Funktioniert fuer den noch nicht gespeicherten Draft-Account, weil
applyDebridAccountStatuses merged (kein Pruning) + emitState.

Kern-Check-Logik unveraendert + weiterhin durch account-check.test.ts gedeckt.
643 Tests gruen, tsc 9 (unveraendert), Build sauber. GUI compile-/build-verifiziert,
im laufenden Electron noch nicht click-getestet.
