Summary:
Fixes T4767. I believe 80% of this was actually caused by the author issue fixed in T5771, but this should help make the other 20% debuggable.
- Record why we didn't autoclose a commit when we process it.
- Show branch autoclose status in the main branch table.
- Show commit autoclose status on the edit screen.
- Add documentation about how to find these statuses and what they mean.
Test Plan:
- Read documentation.
- Viewed branches and hovered over the various states.
- Viewed commits in various states and checked the "Autoclose?" field.
- Pushed some commits and saw autoclose activate.
