Let the CLI cancel a run, not only the browser

#168 promised the same account the same actions through either transport, and
canceling a running run had just become a browser-only action. The queue is
instance-side, so the CLI asks over the key it already pushes with:
`vole run cancel <id>` retires a queued run or asks a running one to stop, checks
the same maintainer capability the page checks, and writes the same audit record.
The server verb takes one repository and one run id and answers one line; the id
is the 26-character one in the run page URL.

The audit action is now `run.cancel` for both transports, because it is the same
action: an operator looking for canceled runs should not have to know which
surface asked.

Part of #162.
