feat(mission-control): sidebar shows queued+running, no auto-monitor seeding

- TaskStarted no longer creates a monitor pane; Panes stays empty unless a
  ConPTY session is explicitly opened
- SeedActive no longer called on construction or ConnectionRestored
- EnsureMonitor / SeedActive kept compiling and functional (internal), just unused
- RefreshQueueAsync now loads Queued + Running tasks, Running sorted first
- QueuedTaskViewModel gains IsRunning + OpenInAppCommand (IRelayCommand)
- Sidebar row is a Button; running rows get RunningTint overlay + "Running" label
- HasQueued is true whenever any queued or running task exists
- New localization keys: missionControl.running (en + de)
- Tests updated: 12 monitor-machinery tests use EnsureMonitor directly;
  3 new acceptance-criteria tests (no-auto-pane, running-first sort, row click)
