Summary:
Allows you to edit or delete comments in appplications which support ApplicationTransactions.
UI/UX stuff:
- The dialogs are rough but I want to do a dialog design pass more generally, @chad has some mocks.
- When you add new mentions via edit, they don't currently count as mentions. I'm not sure what I want to do about this.
- When you edit or delete a comment, we do not publish any notifications about it. I think this is reasonable.
- I didn't separate "delete" out versus "edit"; I assume it will be reasonably intuitive that deleting all the text deletes effectively deletes the comment. I also want to discourage deletion somewhat (we still show the transaction, just show that the comment has been deleted).
Test Plan:
Transaction view, note "Edit" and "Edited" links:
{F26914}
Edit view, has some design issues but I want to do a pass on dialogs in general:
{F26915}
History view:
{F26913}
