/**
 * @title VaultDepositooor
 * @author dextracker
 * @notice A wrapper contract that enables users to deposit their entire token balance into registered vaults
 *         using dynamically constructed calldata with runtime amount injection.
 *         Supports both ERC20 tokens and native ETH deposits.
 *
 * @dev INTENDED USAGE WITH RELAY:
 *      This contract is designed to work with Relay's transferAndMulticall function. The typical flow is:
 *
 *      1. User calls Relay.transferAndMulticall(tokens, amounts, calls, refundTo, nftRecipient)
 *      2. Relay transfers tokens from user to itself using transferFrom
 *      3. Relay executes the Call3Value[] array, which includes a call to this contract's deposit() function
 *      4. This contract deposits tokens into the registered vault on behalf of the user
 *

     *      5. Approves vault to spend tokens
     *      6. Optionally converts amount to 18 decimals (based on vault config)

     *      8. Calls vault with modified calldata
     *      9. Emits Deposit event with results

     *      2. Checks contract's ETH balance (includes ETH sent via Call3Value.value before this call)

     *      4. No conversion needed (ETH is always 18 decimals)
