[I] [Studio][Bug] Prevent data source mutations before the initial list is ready [rocketmq-dashboard]
Aias00 opened a new issue, #2012:
URL: https://github.com/apache/rocketmq-dashboard/issues/2012
## Problem
The Metrics data source tab starts `listDataSources()` on mount, but the **Add data source** action remains enabled while that request is pending.
A user can create a data source before the initial list resolves. The create response is first appended to local state, but the late initial list response then unconditionally calls `setDataSources(sources)` and removes the newly created row from the UI.
## Reproduction
1. Open Settings > Data sources and keep `listDataSources()` pending.
2. Open the create modal and create a new data source successfully.
3. Resolve the original list request with the pre-create snapshot.
The success notification is shown, then the newly created row disappears.
## Expected behavior
- Data source mutations must not start until the initial list snapshot is ready, or list responses must be reconciled with completed mutations.
- The smallest fix should disable the create entry while the initial list is loading.
- Add a deferred-promise regression test proving that a stale initial snapshot cannot overwrite a completed creation.
## Scope
Metrics data source settings UI and focused frontend tests only.
## Track
Track 1 / AI-Native unified control plane.

**Issue Evaluation**
Category: `bug` | Status: **Confirmed**
Verified against `rocketmq-studio` branch: `web/src/pages/settings/index.tsx` (lines 300-313, 375-380).
**Root Cause:** The initial `listDataSources()` is async. If a user creates a data source before the initial list resolves, `handleSubmit` mutates the stale local array (`[...previous, saved]`). When the initial load later resolves, it overwrites the mutation and the newly created data source disappears from the UI.
**Impact:** Data Sources settings page — created data sources can silently vanish if the initial load is slow.
**Severity:** Medium — race condition between initial load and create mutation.
An automated fix proposal will be generated. Reply `/approve` to proceed with PR generation.
