This should work in general because builds update revisions when they complete, to publish a "Harbormaster finished build yada yada" transaction. So either we'll un-draft immediately, or un-draft after the last build finishes.

Fixes T12986. I caught this bug in the changes from D18584: when we moved a large hunk to file storage, we would decompress it but keep the "deflated" flag. This could cause confusion when loading it later. I missed this in testing since I wasn't exhaustive enough in checking hunks and didn't run into a compressed one.
Instead of compressing on `save()`, compress during the normal workflow.
We currently never advise users to run this workflow so I didn't bother trying to clean up possible existing migrations.
Test Plan:
- Ran `bin/differential migrate-hunk` on compressed hunks, moving them to and from file storage. Saw them work correctly and remain compressed.
- Created new small (uncompressed) and large (compressed) hunks, verified they work properly and get compressed (if applicable).
- Used `bin/cache purge --caches changeset` to clear changeset caches and make sure the actual table was being hit.

Ref T12932. For long-lived installs, one of the largest tables tends to be the hunk data table. Although it doesn't grow tremendously fast, it's also well suited to storage in Files instead of the database (infrequent access, relatively large blobs of data, mostly one-at-a-time access), and earlier work anticipated eventually adding support for Files storage.
Make Files storage work, and provide `bin/differential migrate-hunk` to manually test/migrate hunks. This is currently the only way hunks get moved to file storage, but I expect to add a GC step which moves them to File storage after 30 days shortly.
The immediate motivation for this is to relieve storage pressure on db001/db002 so we have more headroom for deploying the Ferret engine and its larger indexes (see also T12819).
Test Plan:
- Used `bin/differential migrate-hunk` to move a hunk to and from file storage, verified it survived intact.
- Downloaded the actual stored file, sanity-checked it. Verified permissions.
- Destroyed a diff with `bin/remove destroy`, saw the hunk and file storage destroyed.
- Verified that going from file -> text destroys the old file properly with `migrate-hunk --trace ...`.

Summary:
See brief discussion in D18554. All the index tables are the same for every application (and, at this point, seem unlikely to change) and we never actually pass these objects around (they're only used internally).
In some other cases (like Transactions) not every application has the same tables (for example, Differential has extra field for inline comments), and/or we pass the objects around (lots of stuff uses `$xactions` directly).
However, in this case, and in Edges, we don't interact with any representation of the database state directly in much of the code, and it doesn't change from application to application.
Just automatically define document, field, and ngram tables for anything which implements `FerretInterface`. This makes the query and index logic a tiny bit messier but lets us delete a ton of boilerplate classes.

Going down this path would have meant a huge pile of stub functions everywhere, I think.

Instead, let ModularTransactions opt in to providing additional data to Conduit, similar to other infrastructure. If a transaction doesn't, the API returns an empty skeleton for it. This is generally fine since most transactions have no real use cases, and I think we can fill them in as we go.
This also probably builds toward T5726, which would likely use the same format, and perhaps simply not publish stuff which did not opt in.
This doesn't actually cover "comment" or "inline comment", which are presumably what PHI14 is after, since neither is modular. I'll probably just put a hack in place for this until they can modularize since I suspect modularizing them here is difficult.
