Pull request overview

This PR addresses Clippy linting warnings by modernizing string formatting syntax and cleaning up imports across the codebase. The changes convert old-style formatted string macros to use inline variable interpolation, reorganize imports according to Rust conventions, and update error handling to use boxed types for large error enums.

Key changes:

• Modernized all println!("{}", var) to println!("{var}") and similar patterns across all logging macros
• Removed unused clap imports (arg, command) and reordered imports to follow Rust conventions (std before external crates)
• Updated error types in sdk/src/models/errors.rs to wrap ClientError in Box<> to reduce enum size, with a custom From implementation
