Bug: voting period on Mocha is incorrect

[rootulp]

Problem

The value reporting for voting period is incorrect for Mocha

Repro steps

1. Navigate to https://mocha-4.celenium.io/
2. Click Constants in sidebar
3. See incorrect value for voting period (see screenshot below). It currently reports 172800s which is 48 hours. But the actual value is 86400000000000 nanoseconds which is 24 hours.

$ grpcurl -d '{"subspace": "gov", "key": "votingparams"}' celestia-mocha-grpc.publicnode.com:443 cosmos.params.v1beta1.Query/Params
{
  "param": {
    "subspace": "gov",
    "key": "votingparams",
    "value": "{\"voting_period\":\"86400000000000\"}"
  }
}

Feedback

1. The text says nanoseconds but the value shows the unit "s" for seconds. IMO you could make it super readable for end-users by showing "1 day" or "24 hours" instead of the nanosecond or second value.
2. The sidebar name "Constants" is slightly misleading because a lot of these values can be changed via governance. See https://celestiaorg.github.io/celestia-app/parameters_v3.html. One option is to rename it from "constants" to "parameters"
