Summary:
Ref T603. Herald transcripts potentially leak a bunch of content (task text, revision/commit content). Don't let users see them if they can't see the actual objects.
This is a little messy but ends up mostly reasonable-ish.
Test Plan:
- Verified that transcripts for objects I couldn't see no longer appear in the list, and reject access.
- Verified that transcripts for objects in applications I can't see reject access, albeit less gracefully.
