feat: add serialization and deserialization for tasks
Introduced methods to serialize and deserialize tasks to enable saving and loading Kanblendar state. This addition facilitates persistence and recovery of task data, ensuring continuity. Adjusted task element creation and placement to maintain task integrity during deserialization.
