Make archive confirmation number shortcuts act immediately (#44744)

## What changed

Allow `2` to confirm archiving a task and its child agents in the agents overview without an additional confirmation keystroke. Keep explicit confirmation for permanent deletion.

## Testing

Add a regression test verifying that `1` cancels and `2` dispatches the archive action, with both shortcuts closing the confirmation popup.
