Tasks visibly progress: Run → In Progress (+ close drawer); approve → In Review

A task assigned to an agent never moved, so it looked like nothing happened. Now:
- Clicking Run moves the task from Backlog to In Progress and closes the drawer.
- When an approved artifact lands on a task, it moves to In Review (unless already Done),
  so the delivered result is visible on the board instead of sitting in Backlog.
