🔧 Update MathJax configuration and enhance LaTeX processing

- Replaced the MathJax script source in index.html to use 'tex-chtml-full.js' for improved rendering capabilities.
- Added 'mhchem' package to MathJax configuration in mathjax-config.js for better chemical equation support.
- Removed the obsolete 'tex-mml-chtml.js' file.
- Enhanced error handling in LaTeX processing functions within latex.js, including logging for MathJax rendering success and errors.
- Improved Markdown rendering to maintain original formatting for list items and handle math expression placeholders more effectively.
