GET /metadata/obv3 has additional environment configuration

`domain` (`name`, `version`, `chainId`, `verifyingContract`)	the EIP-712 domain — pass `meta.domain` to `signTypedData`
`activeAsset.baseToken`	the `baseToken` field of every order
`activeAsset.escrowAddress`	equals `domain.verifyingContract`
`activeAsset.decimals`	converting whole tokens to base units
