Initial commit: Learning Lab Express

Includes fixes found while reviewing the app:
- Results: open each result by a type+agent+id key, so a video and a
  material draft with the same id no longer open each other's popup
- AuthGate: clear the query cache during render, before pages build their
  queries, and remount pages on organization switch (pages no longer stay
  on skeletons for up to a minute after sign-in or refresh)
- Instruction: keep only failed rules after a partial approve, so retrying
  does not create the successful schedules twice; drop the monthly note
  once count or frequency is edited
- Parser/schedules: never schedule a count below one
- Audio: ignore the end event of a cancelled utterance when changing speed
- Downloads: revoke the object URL later so Safari/Firefox can read it
- Results: refetch SCORM content when any part's revision changes; show a
  failed video as failed instead of "still rendering"
