fix: update source-reading tests that drifted from the code

- test_transport_contracts: CreateGroupPage was refactored into a
  routing wrapper; assertions now read CreateGroupFormSimple
- test_task_lifetime: _spawn now uses an _on_done wrapper instead of
  a bare self._tasks.discard callback; assertion checks both parts
- test_video_buffer_ceiling: target the real updateend handler, not
  the settled() utility; add awaitingInitRef to the MSE harness scope
- test_video_seek: silence debug console.log in window_leak harness
  so it does not pollute the JSON output
