Add labels to tasks for better organization and filtering

Introduce a label system to categorize tasks, enhancing organization and enabling filtering. The initial setup includes default labels like 'Work', 'Personal', 'Urgent', and 'Study', with fixed IDs for consistent data management. The client-side now supports associating labels with tasks, and the `TaskCard` component fetches labels to display their corresponding colors. The server-side storage has been updated to use predefined IDs for these default labels.
