[Refactor]: Fix Clippy warnings (uninlined_format_args & more)

[jalalvandi]

What needs refactoring?

There are currently several Clippy warnings being ignored in CI, specifically related to clippy::uninlined_format_args.

Why should this be refactored?

for better performance and code style

How could it be improved?

We should:

• Replace format!("{:02}", x) style with format!("{x:02}")
• Replace write!(f, "{}", var) with write!(f, "{var}"), etc.
• Review other Clippy suggestions while we're at it
• Re-enable -D warnings in CI

This was temporarily disabled in #XYZ for faster iteration, but we should clean it up before next release.
