Render edge failure message

Context

There is not current implantation to display any ThreadRun errors to the user. The information that is currently implemented is not enough to differentiate the TaskRun error vs ThreadRun error. @eduwercamacaro will have to update the server to accommodate this issue.

For example:

{
  "id":  {
    "wfRunId":  {
      "id":  "6ef3902941bf48ab9163d1f545efdc45"
    },
    "threadRunNumber":  0,
    "position":  1
  },
  "wfSpecId":  {
    "name":  "example-basic",
    "majorVersion":  1,
    "revision":  0
  },
  "failureHandlerIds":  [],
  "status":  "COMPLETED",
  "arrivalTime":  "2024-05-31T20:38:09.616Z",
  "endTime":  "2024-05-31T20:38:09.645Z",
  "threadSpecName":  "entrypoint",
  "nodeName":  "1-greet-TASK",
  "failures":  [
    {
      "failureName":  "VAR_SUB_ERROR",
      "message":  "Failed evaluating edge with sink node 2-exit-EXIT: Mutating variable another with operation ASSIGN: Couldn't convert strVal to INT For input string: \"Hello, World!\"",
      "wasProperlyHandled":  false
    }
  ],
  "task":  {
    "taskRunId":  {
      "wfRunId":  {
        "id":  "6ef3902941bf48ab9163d1f545efdc45"
      },
      "taskGuid":  "d5210b7b89f54d52af4e7ee84e0d5d45"
    }
  }
}

It should check if $.failures[] is not null or empty and change the node status to ERROR. Rendering the $.failures[].failureName and $.failures[].message in a error box.

You can reproduce this issue with this WfSpec in java

return new WorkflowImpl(
            "example-basic",
            wf -> {
                    WfRunVariable theName = wf.addVariable("input-name", VariableType.STR).searchable();
                WfRunVariable another = wf.addVariable("another", VariableType.INT).searchable();
                wf.execute("greet", theName);
                wf.mutate(another, VariableMutationType.ASSIGN, "Hello, World!");
            }
        );

We still need to discuss this as a team about how to implement this to make the UX enjoyable
