feat(ui): answer a running task's question inline in Mission Control

TaskMonitorViewModel surfaces a pending AskUser question (TaskQuestionAsked /
TaskQuestionResolved events) with an AnswerDraft + SubmitAnswerCommand that calls
the new IWorkerClient.AnswerTaskQuestionAsync; MonitorPaneView shows an accent
question banner with an input box above the terminal. Pending question is cleared
on answer/resolve/finish and re-hydrated on attach via GetPendingQuestionAsync.
en/de localization for missionControl.question.*; test fakes updated.
