refactor(Draft): Replace latest() with latest_ref() and data() with data_mut() in multiple files for improved mutability handling and consistency across the codebase (#3987)

* feat: add benchmarking for draft operations and new draft management structure

* Refactor Config Access: Replace `latest()` with `latest_ref()` and `data()` with `data_mut()` in multiple files for improved mutability handling and consistency across the codebase.

* refactor: remove DraftNew implementation and related benchmarks for cleaner codebase
