feat(ui): add "move to list" to the task row context menu

Reuses the existing drag-drop move (MoveTaskToListAsync) so the same
running/worktree guards apply — only ListId changes.

Also count WaitingForReview tasks (not Done-with-a-branch) for the
review portion of the status pill, and localize the pill and open-task
count strings that were still hardcoded English.
