feat(help): enhance help command with interactive UI components

Introduce a comprehensive interactive help system for the Tux bot,
featuring category browsing, command details, subcommand navigation,
and pagination for large command groups. This update includes:

- A new `help_components.py` module for UI components like select
  menus and navigation buttons.
- A `help_utils.py` module for utility functions to format and
  categorize help content.
- Refactored `help.py` to integrate the new UI components and
  utilities, improving the user experience with a structured and
  interactive help interface.

These changes aim to provide users with a more intuitive and
navigable help system, making it easier to explore and understand
the bot's capabilities.
