Pull Request Overview

This PR refactors the pretty_name_mode type and related constants in the /ui2/cl_json class to use a more efficient single-character representation instead of strings. The change standardizes the type usage across all method signatures that accept pretty_name parameters.

Key Changes:

• Changed pretty_name_mode from string to single-character type (c LENGTH 1)
• Updated constant values to use single characters ('L' for low_case, 'X' for camel_case)
• Enforced type consistency across all method signatures using pretty_name parameters
