- Added `automatic_tasks.go` and `automatic_tasks_test.go` for backend logic and testing of automatic tasks. - Created `automatic_tasks_test.go` to validate task claiming and deletion behavior. - Developed `AutomaticTasksPage.tsx` for frontend management of automatic tasks, including task creation, editing, and execution. - Integrated device and eSIM profile selection for task configuration. - Implemented automatic task scheduling and retry logic in the backend.
