execute: drain newly-approved jobs mid-run, use strict shared parseId

Queue previously processed a snapshot of pending jobs — anything approved
after Run-all clicked sat idle until the user clicked again. Now, when
the local queue drains, re-poll the DB once for newly-approved jobs
before exiting.

Also swap the looser local parseId (Number.parseInt accepted '42abc')
for the strict shared parseId in server/lib/validate.ts.
