MengMengCode 8a260e86f1 Implement automatic task management with CRUD operations and UI integration
- 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.
