Intermittent syntax error in `consume.ts` - Unexpected end of JSON input

Sentry is picking up an occasional error with converting a response payload to json in message consumption (`consume.ts`).

Sentry Issue: [VSCODE-EXTENSION-AJ](https://confluent.sentry.io/issues/5943076343/?referrer=github_integration)

```
SyntaxError: Unexpected end of JSON input
File "..\src\consume.ts", line 514, in
const payload = await error.response.json();
...
(2 additional frame(s) were not displayed)
```

Start at src/consume.ts line 514, where message-consumption error handling calls error.response.json(), and review the surrounding response path. Use the linked Sentry report to investigate the intermittent incomplete JSON response; the issue is done when the failure is understood and the handling is verified not to produce this syntax error.
