[12.x] Add allowedUrls through preventStrayRequests

[rabrowne85]

The purpose behind Http::preventStrayRequests() is great - it stops any stray requests from hitting endpoints.
However, this also means that if you’re trying to use SSR to check the output from something like Inertia, those requests will be blocked and a StrayRequestException will be thrown.

This PR expands the existing Http::allowStrayRequests() method to accept an array of “allowed” URLs.
For example:

Http::allowStrayRequests([ 'http://127.0.0.1:13714/*', ]);

To keep things fully backward-compatible, calling allowStrayRequests() without arguments still turns preventStrayRequests off entirely, as it did before.

Both the Http\Client\Factory and Http\Client\PendingResponse classes have been adjusted to accept and pass the allowed list of URLs.

I’ve added a simple test to ensure the allow-list logic works.
I avoided adding a test that actually hits a real endpoint, since depending on when/how the tests are run, the result could vary - even for 127.0.0.1.
