Pull Request Overview

This PR standardizes Ether amount formatting by replacing manual wei-to-ether conversions with the format_ether utility across provider operations, CLI commands, and an example.

• Imported and used format_ether in place of manual division by 10^18.
• Cleaned up various Console::info and println! calls for consistency.

• [nitpick] The label "Balance" is ambiguous in the context of both token and ETH balances; consider making it more specific (e.g., "Token balance").

            Console::info("Balance", &format_ether(balance));

crates/worker/src/operations/provider.rs:274

• [nitpick] This duplicate log also uses the generic label "Balance"; renaming it to distinguish token balance from ETH balance would improve clarity.

            Console::info("Balance", &format_ether(balance));
