Add e2e tests for gRPC requests and CLI commands (#13)

- Add E2E tests following pattern suggested in cosmos-sdk docs:
  https://docs.cosmos.network/v0.50/build/building-modules/testing#end-to-end-tests
  - Tests for gRPC requests
  - Tests for manually configured CLI commands
- Add a CI workflow to run these E2E tests
