enhance: Do not Suspense fallback warning in NextJS server-side

[ntucker]

Motivation

The SSRDataProvider component was using BackupLoading as its Suspense fallback, which displays an "Uncaught Suspense" warning in development mode. This warning is misleading during Next.js server-side rendering because:

• Suspense during SSR is expected behavior for data fetching
• The warning suggests user error when none exists
• The message can appear in the HTML output before hydration

Solution

Replace the BackupLoading fallback with null in SSRDataProvider. This silences the confusing warning while maintaining the same functional behavior - the outer Suspense boundary still catches suspense during SSR, just without rendering a misleading development message.

---

Note

Removes the misleading "Uncaught Suspense" dev warning during Next.js SSR by changing the Suspense fallback in SSRDataProvider.

• In SSRDataProvider, replace BackupLoading with null as UniversalSuspense fallback to avoid the warning during expected SSR suspense
• Add a changeset for a patch release of @data-client/react
• Update the v0.16 release blog with the improvement note
