fix(activity): a run nothing here has open reads as interrupted, a rollback sums a stopped run's spend

- The scheduler keeps one registry of the runs this process has open, for the interval jobs and the
  ad-hoc runs alike. A row the table still says is `running` but no run here has open (its outcome
  failed to write) reads as interrupted, as the next start's sweep will close it: no pulsing dot
  beside "No run recorded yet".
- Migration 0109's downgrade sums a still-running run's quota events into its spend before the link
  to them is dropped, as the startup sweep would.
- A test holds that a dialog closing onto the same address leaves an open log line open.
