Build separate comments for each inline comment in Audit

Summary:
Ref T4896. Moves us closer to migrating comments to transactions by building a transaction per inline.

This makes the UI a little wonky, and it will get slightly worse until we swap to the new UI and grouping/collapsing starts working. It's still usable, there's just a box per inline.

Test Plan:
  - Added a comment.
  - Added an inline comment.
  - Added a comment and an inline comment.
