[PM-6484] Revert "[PM-5277] Migrate Sync Service to State Provider (#7680)" (#8157)

* Revert "[PM-5277] Migrate Sync Service to State Provider (#7680)"

This reverts commit 78008a9e1e.

Includes a noop migration builder that allows us to bridge over the deleted migration

* Prefer revert migrations to noop

this revert avoids the need to change behavior between released vs unreleased migrations and keeps some dangerous code out of the repo :success:

* Update ordering of badge settings migrator to be consistent with `rc`, which was cut with only up to version 25

* Fix missing type import
