ref(core): Remove beforeSendSpan null return warning

[msonnb]

Remove the unconditional warning when beforeSendSpan returns null, saving ~90B (compressed) / ~200B (uncompressed).

The type already disallows returning null since v9. Keeps the runtime fallback to the original span for JavaScript callers, with one regression test covering the shared behavior.
