Feat/performance improvements

[fan-turintech]

This code update includes several improvements to enhance efficiency, readability, and maintainability across various parts of the application. Key changes include:

1. Modernized command execution: Replaced less secure os.system() calls with subprocess.run() or subprocess.check_call(), improving security and error handling.
2. Optimized data structures: Changed assets_deps from a list to a set, improving efficiency in dependency management.
3. Simplified code logic: Refactored conditional statements into more concise structures, such as using dictionaries instead of multiple if-elif statements.
4. Enhanced string formatting: Adopted f-strings for more readable and efficient string formatting throughout the code.
5. Improved file handling: Modified file opening modes to avoid unnecessary operations.
6. Streamlined asset configuration: Simplified the process of generating asset configurations and loading JavaScript dependencies.

These changes collectively result in more pythonic, secure, and efficient code. The improvements should lead to better performance, easier maintenance, and reduced potential for errors.
