The commit refactors the server-side modules of the Roxy-WI web interface to use JSON-based APIs for improved data exchange. Specifically, methods for user, group and SSH management have been updated to accept and return JSON data. Simultaneously, error handling is improved to give more informative responses instead of plain strings. The client-side JavaScript code is also refactored to accommodate these changes. Additionally, some minor corrections are made in the UI templates.
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.
This commit applies exception handling for the network operations methods and removes unused/commented-out code. The added exception handling checks for incorrect input to nettools methods and raises explicit exceptions with descriptive messages. This dramatically simplifies the debugging process, providing better visibility into runtime errors.
