test(e2e): update kvtool & e2e tests (#1659)
* add Cdp querier to Chain

* verify funded account has sufficient balance

* return error for nonzero status codes

* update e2e test for eip712 signing

complex eip712 workflow now uses x/cdp instead of x/earn vault

* update to master kvtool

* reset e2e env variables
