Gets one of an automation's spend limits, with what it has spent in the current window

An automation spends through several agents — the ones its stages run, the one that holds its questions as conversations, the one that writes its report — and each agent keeps its own limits. This limit is on the automation as a whole: every production run the automation caused counts, whichever agent made it, and only those. An agent's limits still apply beside it; a run has to fit under both. A `null` body means no limit is set for the window, not that the automation is free to spend: its agents' limits still bind. A 404 means the automation does not exist or the caller cannot reach its Application.
