LGTM, paired on this so we should wait for an additional approval, but testing locally it all works and the BlockApi is accessible via 9090 using an embedded v3 app.

## Overview

Due to the multiplexer copying start command functionality from the sdk,
I discovered that running native apps (for example, v4) will not expose
the core BlockAPI when through the multiplexer, i.e. the changes in
celestiaorg/cosmos-sdk#455 do not take effect
which spin up the core BlockAPI in-process.

The BlockAPI is however available right now when:
- Running embedded apps (for example, v3) through the multiplexer. 
- Running a v4 standalone app without the multiplexer.

The replication of start command code being distributed and copied
amongst different places is extremely error prone to manage, and quite
frankly, its spaghetti.
