This commit introduces the ability to handle log files through the API and provides a new log viewing page. The API now supports GET and DELETE methods for log file operations, allowing retrieval and deletion of log contents. A new log.html page has been added for viewing logs in the browser, with automatic refresh every 5 seconds and styling based on log levels. The app.go file has been updated to include a GetLogFilepath function that retrieves or generates the log file path. The NewLogger function now accepts a file parameter to enable file logging. The main.js file has been updated to include a link to the new log.html page. This enhancement improves the observability and management of the application by providing real-time access to logs and the ability to clear them directly from the web interface.
