Queue::fake six V2RunDetailViewTest tests + available_at-aware drain

Six RunDetailView tests were racing real testbench queue workers in CI
under the same bucket A pattern as the V2WorkflowTest conversions in
d042ea9 / 561a441. They pass reliably on local docker but time out at
5–30s on contention-bound GitHub Actions runners.

Convert them to the Queue::fake + drainReadyTasks pattern so they are
self-contained, and teach V2RunDetailViewTest's local drainReadyTasks
helper to respect `available_at` just like the real worker does (same
patch shape as d042ea9 on V2WorkflowTest). Without the available_at
filter, drainReadyTasks would fire future-scheduled timer tasks early
and the test would observe a completed workflow when it expected a
parked one.

Clears 6 CI-only MySQL failures under #399:
  * testRunDetailViewIncludesCommandsActivitiesAndTimelineForCompletedSignalRun
  * testRunDetailViewKeepsActivityDetailWhenActivityRowDrifts
  * testRunDetailViewFallsBackToTypedActivityHistoryWhenActivityRowIsMissing
  * testRunDetailViewKeepsSignalWaitCommandMetadataWhenCommandRowsDrift
  * testRunDetailViewIncludesChildWaitAndLineageForParentRun
  * testRunDetailViewReturnsTypedPayloadsNotPhpSerializedStrings
