## Description

Closes: #9800

The following is a breaking fix to #9800. In the non-breaking fix, the initialization logic was moved out of `InitializeAndSeal` but the API was preserved. I've now removed `InitializeAndSeal` and replaced it with just the `Seal` function, which may be called much more cleanly in `app.go`
