Summary:
Ref T11179. Ref T4768. Currently, on `master`, if two users open "Edit Revisions" at the same time, then add revisions A and B, only the last state wins (just "B").
Instead, apply these as "add A" and "add B" so they merge in a natural way.
Test Plan:
- Opened edit dialog in two windows.
- Added "A" in one, "B" in the other.
- Saved both.
- Saw "Added A" and "Added B" transactions, instead of "Added A" and "Removed A, added B".

Summary: Ref T11179. This is basically a "pro" controller to replace the SearchAttach controller. It does basically the same stuff, just in a (mostly) more modern and modular way.
Test Plan:
- Added and removed mocks.
- Added and removed revisions.
- Everything worked just like it did before.
