Explain that daemon set-password needs a terminal when stdin is piped (#5358)

* Explain that daemon set-password needs a terminal when stdin is piped

The password prompt only resolves on a keypress from a terminal. With
stdin piped or redirected it never settled, so Node exited 13 with an
unsettled top-level await warning and no message. The command now fails
with PASSWORD_TTY_REQUIRED and points at PASEO_PASSWORD.

Closes #5350

* Assert the set-password terminal error message
