Fix D1 adapter using wrong endpoint (/execute -> /query)

The Cloudflare D1 REST API exposes /query (and /raw) per
https://developers.cloudflare.com/api/resources/d1/subresources/database/methods/query/
but the adapter was hitting /execute, which returns 404.

The miniflare-based integration test was passing because the mock worker
was written to match the broken path — update the mock and the test
fixture's setup client so the integration test exercises the real
Cloudflare path.

Fixes #159
