test(11-07): cover jobs, scheduler and lagoon seams branch by branch

- conga: TestOutcome*, TestCancelQueuedNeverRuns, TestCancelRunningCancelsCtx,
  TestStopJobFromWorker, TestManagerPHPSemantics, principal, delay,
  registration, worker and queue-setting branches; TestQueueClear and
  TestQueueWork move to commands_test.go with the batch/state and
  queue-filter cases (coverage 92.5%)
- scheduler: validation, ordering, missing catalog, log writer, dueAt
- lagoon: TestQueueMigrationsUpDown (River v7 + summer_jobs, rollback,
  idempotent rerun), OnDatabase isolation, Transaction edges
- bonfire TestCallEdges, pact TestCadence
