/**
 * Fetches the on-chain state of a Morpho Blue market using its unique key.

 * This function queries the Morpho subgraph to retrieve the current market state
 * (liquidity, borrow/supply stats, APYs, etc.) associated with the provided `uniqueKey`.
 *
 * @param walletProvider - Connected EVM wallet instance.
 * @param args - Object containing a valid `uniqueKey` (bytes32) to identify the market.
 *
 * @returns A Promise resolving to the state of the specified market,
 *          or `null` if the market is not found or has no recorded state.
 *
 * @throws Will throw an error if:
 *  - Network or chainId is missing or invalid.
 *  - The network is not supported by Morpho subgraph.
 *  - A subgraph call fails or returns an invalid result.
