fix: delete node details state

[tujvyong]

Why

I would like to remove the following code, as I felt it was unnecessary and the intent was not clear.

    const nodeDetails = await nodeDetailManager.getNodeDetails({
      verifier: "test-verifier",
      verifierId: "test@example.com",
    });

Details

Use fnd-base instead of the above torusresearch/fetch-node-details@v13.0.0/packages/fnd-base/src/endpoints.ts#L3

Closing since we're moving to a different interface altogether in #23
