// ── Regression test for the "declined payment still granted access" bug ──────
// PayPal's v2 capture-order endpoint can respond with HTTP 2xx even when the
// charge itself was declined or held for review — the failure only shows up
// in the response body's status field (e.g. capture.status: "DECLINED" or
// "PENDING"), not as a thrown HTTP error. Before the fix, captureOrder() only
// guarded against a *thrown* error from the provider and unconditionally
// granted the tier on any non-throwing response. These tests pin the fix:
// a non-COMPLETED capture must mark the payment failed and must NOT create
// or extend a user_tiers row.
