Implement app_v2 wiring

[fmorency]

Using app_v1 is causing the TestAppImportExport simulation to fail in CosmosSDK v0.50.6.

I see a similar behavior on #76.

KV stores are different: 26 key/value pairs in store A and 0 key/value pairs in store B

The issue doesn't occur when using app_v2 wiring in CosmosSDK. Implement app_v2 wiring in this application and see if it fixes the problem.

manifest-ledger depends on ibc which is incompatible with v2 wiring.
