This commit adds a new TaskService class to handle all task-related operations, including task creation, listing, and artifacts management.
- Implemented methods for creating a new task (createTask).
- Added functionality to retrieve details for a specific task (getTaskDetails).
- Enabled listing all tasks with optional pagination (listAllTasks).
- Enabled listing all artifacts for a specific task with optional pagination (listTaskArtifacts).
By encapsulating these operations within the TaskService class, this commit provides a clean and centralized way to interact with the backend for task functionalities, making the application more maintainable and easier to extend.
