Voice parks a routine proposal, it never accepts it (V-367)

Accepting a proposed routine gives the tick loop a standing new reason to
speak. DESIGN.md § "surface caps authority" puts that at layer 3, and says
voice is structurally incapable of layer 3 because a room mic is reachable
by anyone in the room. The /routines button was gated at step-up; the voice
path accepted outright. The two surfaces disagreed, so one of them was wrong.

A spoken "да" now leaves the row 'proposed' and sends him to /routines,
where the gated button is. A spoken "нет" still dismisses: declining does
not move the boundary outward, so voice keeps it.
