fix(volition): rest an action on the belief about that action

An intention's supporting beliefs came from a text search on the target,
and ties on rank and confidence had no order, so a verification miss could
revise an unrelated belief about the same service. Beliefs that mention the
proposed action now come first, and belief search breaks ties by id.

The incident scenario asserts the first support is the belief about
restarting, and waits for the blocked intention and the procedural memory
instead of reading them once.
