Annotate app.go

[faddat]

Closes: #XXX

Description

While building Craft Economy and trying to become more familiar with the cosmos SDK, and familiarize others, I ended up annotating app.go, and found it really helpful, so I figured that I might as well annotate Osmosis' app.go, too!

Wait what, why did merging sunny's PR close this, I thought github auto-updates PRs to re-target main >:(

[ValarDragon]
