Refactor code formatting for consistent 4-space indentation and improved readability

[Lucas-Developer-Off]

Problem

The codebase currently has inconsistent indentation and spacing, which affects readability and maintainability.

Solution

• Refactor all source files to use a consistent 4-space indentation.
• Ensure code is well-spaced for readability, but avoid excessive blank lines.
• Apply consistent formatting across all languages and files (JS, JSON, HTML, etc.).
• Do not overdo spacing; keep the code clean and readable.

Acceptance Criteria

• All files use 4-space indentation consistently.
• Code is easier to read and maintain.
• No unnecessary excessive spaces or blank lines.
• Formatting matches team/code style guidelines.

Additional Notes

This change is style-only and should not alter any logic or functionality.
