fix(localization): de.json-Konsistenz-Pass und restliche harte EN-Strings

Queue/Task(s)/Gate in deutschem Fliesstext auf Warteschlange/Aufgabe(n)/
Limit-Stopp vereinheitlicht, columnTask-Keys auf AUFGABE angeglichen,
Kill-Tonalitaet (closeSession/killSessionTip) ehrlich-destruktiv gemacht.
RepoImportModalViewModel.CreateButtonText und alle Installer-Check-Messages
(Git/GitIdentity/WriteAccess/ClaudeCli/ClaudeVersion/ClaudeAuth/
PermissionModeAuto/Ports) ueber Locale-Keys geroutet statt hartem Englisch,
mit dem bestehenden TrExtension.Localizer-Fallback-Muster.
