Codex Security Cloud fails to create/save new security scan with internal server error

What issue are you seeing?

I am seeing a Codex Security Cloud bug in ChatGPT/Codex Web where creating or saving a new security scan configuration fails.

The UI shows this error:

Failed to save scan settings: The server had an error processing your request. Sorry about that! You can retry your request, or contact us through our help center at help.openai.com if you keep seeing this error. (Please include the request ID [redacted] in your email.)

### What steps can reproduce the bug?


**What steps can reproduce the bug?**
```markdown
1. Open ChatGPT/Codex Web.
2. Go to Codex Security Cloud scans.
3. Click New scan.
4. Select a repository, branch, environment, and scan history window.
5. Click Create / Save / Run Scan.
6. The scan is not created, and the UI shows an internal server error.

I also saw a browser console error earlier:

```text
QuotaExceededError: Failed to execute 'setItem' on 'Storage':
Setting the value of 'cache/user-[redacted]/[workspace-id-redacted]/system-connectors' exceeded the quota.
key: system-connectors

### What is the expected behavior?


**Expected behavior**
```markdown
Codex Security Cloud should successfully save the scan configuration and create/start the new security scan.

If the scan cannot be created, the UI should show a specific actionable error instead of a generic internal server error.
