/**
 * Server-side function to fetch eligible payment methods from the PayPal API.
 *
 * Use this in server environments (Next.js server components, Remix loaders, etc.)
 * to pre-fetch eligibility data before hydrating the client. Pass the response
 * to the `PayPalProvider` via the `eligibleMethodsResponse` prop.
 *
 * @param options - Configuration for the eligibility request
 * @param options.headers - HTTP headers for the request, including the `Authorization` bearer token
 * @param options.environment - Target environment ("sandbox" or "production")
 * @param options.payload - Optional request payload with customer/purchase details
 * @param options.signal - Optional AbortSignal for request cancellation
 * @returns Promise resolving to the eligibility API response
 *
 * @example
 * // Next.js server component
 * const response = await useFetchEligibleMethods({
 *     headers: {
 *         "Content-Type": "application/json",
 *         Authorization: `Bearer ${clientToken}`,
 *     },
 *     environment: "sandbox",
 *     payload: { purchase_units: [{ amount: { currency_code: "USD" } }] },
 * });
 *
 * <PayPalProvider eligibleMethodsResponse={response} ... />
