feat: share finish stop and cancel across the board

Proposal visibility is already global; this change makes finish, stop,
and cancel shared queue-management actions so any user can unblock the
single worker and shared queue. Confirm, adjust, follow_up, and
start_next remain owner-only. Assistant/bootstrap copy, /help, /list,
and runtime checks now align with that split.
