Pull Request Overview

This PR standardizes account management by implementing named accounts through hardhat-deploy and changes terminology from "admin" to "owner" for consistency. The changes centralize account retrieval using getNamedAccounts() instead of directly accessing signers by index.

• Replaced direct signer access with named account pattern using getNamedAccounts()
• Updated configuration to define deployer and owner named accounts with fallback logic
• Renamed "admin" references to "owner" for consistent terminology
