Inspect test RPC health, active forks, and testing policy limits. Use this before calling [`POST /v1/testing/fund-wallet`](/tools/testing_fund_wallet) to confirm the test RPC infrastructure is available.

This endpoint is only available on staging and production deployments with testing tools enabled.
