/**
 * Supplies a specified amount of loanToken into a Morpho Blue market on behalf of the connected wallet.
 *
 * This function:
 * 1. Validates input and ensures asset amount is greater than zero.
 * 2. Fetches market configuration using the provided marketId.
 * 3. Reads the loanToken's decimals and parses the asset amount into atomic units.
 * 4. Checks allowance and, if necessary, approves the Morpho Blue contract to spend tokens.
 * 5. Prepares the calldata for the `supply` function on the Morpho Blue contract.
 * 6. Sends the supply transaction and returns the transaction hash and receipt.
 *
 * @param walletProvider - Instance of {@link EvmWalletProvider} connected to the user's wallet.
 * @param args - Validated input matching {@link SupplySchema}, containing:
 *   @property {string} assets - Amount of loanToken to supply (as a string in human-readable units).
 *   @property {string} marketId - Unique market identifier (bytes32 hex string).
 *
 * @returns A Promise resolving to an object containing:
 *   @property {string} loanToken - The address of the loan token used.
 *   @property {string} txHash - The hash of the supply transaction.
 *   @property {object} receipt - The transaction receipt from the network.
 *
 * @throws Will throw if:
 *   - The input `assets` value is zero or invalid.
 *   - Market configuration cannot be fetched or is invalid.
 *   - Approve call fails, or allowance check/setting fails.
 *   - The transaction fails to send or confirm.
