to the governance timelock this way once its owner-driven setup has run.
fn set_admin(env: soroban_sdk::Env, new_admin: soroban_sdk::Address)Set the pause flag (admin only). The bool shape is what the governance guardian's
guardian_pause(target, paused) invokes, so LockYield is reachable by the same emergency
brake as the engine; pause / unpause are the
no-arg sugar over it.
Once enable_emergency has run, the pause can no longer be
lifted through either shape — emergency is irreversible and implies pause.
