Contract verification fails on UI for multi-file solidity contracts

[akshat-zeeve]

🐛 Bug Report

📝 Description

Contract verification fails on the zkSync Explorer UI when using multiple file contracts

🔄 Reproduction Steps

1. Prepare a smart contract that uses imports and spans across multiple Solidity files
2. Try verifying the contract using the zkSync Explorer UI
3. Verification fails with the error:
   Deployed bytecode is not equal to generated one

🤔 Expected Behavior

The contract should verify successfully if the correct constructor arguments and compiler settings are used, just like it does when verified using Hardhat

😯 Current Behavior

Verification fails on the UI for multiple file contracts, but works when using Hardhat
For single file contracts, both UI and Hardhat verification succeed
