Revise log system

[babarot]

What

• Restructured the logging package to be more modular and maintainable
• Split the logging functionality into separate files:
  • types.go: Type definitions and constants
  • styles.go: Style definitions and utility functions
  • options.go: Configuration options and setters
  • log.go: Core logging functionality
• Added new text styling utilities (Highlight and UnderBold)
• Enhanced logging messages with structured grouping and better formatting
• Fixed IMPORTANT log level integration with default styles
• Improved log output consistency across different storage types
• Moved environment-related code to utils package for better organization

Why

• The code structure was becoming difficult to maintain with multiple responsibilities in single files
• Style definitions were scattered across the codebase, making it hard to maintain consistent styling
• Log messages lacked proper structure and grouping, making debugging more difficult
• The new structure makes it easier to extend logging functionality while maintaining backward compatibility
• Better encapsulation of logging internals allows for easier testing and maintenance
