Update app.py and COMMON_ERRORS.md for improved clarity and functionality: Correct the comment in app.py from "Kontext-Prozessor" to "Context-Prozessor" for better understanding. Enhance COMMON_ERRORS.md by adding new common errors and solutions related to TypeScript usage, OAuth implementation, and neural network background animation issues. Update mindmap page scripts to ensure proper global availability of functions and improve error handling for user notifications. Adjust template references for Tailwind CSS and Alpine.js to support both CDN and local versions, ensuring better resource loading and compatibility.
