- Changed the default language in `index.html` from Russian to English, updating the title and button aria-labels for improved accessibility. - Refactored the `buildFetchOptions` function in `api.js` to include an optional external abort signal, enhancing request management. - Updated `fetchDuties` and `fetchCalendarEvents` to support request cancellation using the new abort signal, improving error handling. - Added unit tests for the API functions to ensure proper functionality, including handling of 403 errors and request cancellations. - Enhanced CSS styles for duty markers to improve visual consistency. - Removed unused code and improved the overall structure of the JavaScript files for better maintainability.
