Stops the Nuxt server SDK from flushing on every HTTP response, which shipped a client_report envelope per request instead of aggregating outcomes on the flush interval.

Swaps the eager vercelWaitUntil(flushSafelyWithTimeout()) for flushIfServerless(), so serverless still flushes eagerly while a long-running server is a no-op.

closes #23306

The http `responseHook` called `vercelWaitUntil(flushSafelyWithTimeout())`, which
evaluates the flush eagerly regardless of platform. On a long-running server this ran
`flush()` on every HTTP response, shipping each pending outcome as its own
`client_report` envelope instead of aggregating it on the flush interval.

Use `flushIfServerless()` instead, which only flushes on serverless platforms and is a
no-op on a long-running server.
