Removed the `check_version.html` template and moved version checking to `script.js`. This refactoring simplifies the codebase by consolidating version check handling into JavaScript, removing deprecated HTML templates, and enhancing the backend logic and API routes.
The error handling has been refactored in the Roxywi overview and routes files to raise and return more comprehensive exceptions. Unnecessary commented out JSON parsing code in the service installation file has been removed for better code clarity. Aside from these, various minor grammar and formatting fixes have been made to the README.md to improve readability.
