 * Merges payable sources the wallet-assets API doesn't index — an xStock the
 * user holds + its wrapper — into the holdings map.
 *
 * Note: xStock/Nado-only today; possibly deprecate once backend supports these natively.
 *
 * - Gated by `enable-rpc-xstock-assets` (off by default) → no RPC reads, nothing injected.
 * - Single seam in `useWalletAssetHoldings` so keys can't drift across consumers.
 * - Injects only what the API omits (never clobbers its price/USD); gating lives upstream.
