Update Task Status Terminology from "COMPLETED" to "DONE" in Frontend and Backend

Overview:

This ticket aims to change the task status terminology used in both the frontend and backend of our application from "COMPLETED" to "DONE." This update is essential for maintaining a consistent user experience and data integrity.

User Stories:

• As a developer, I need to modify the frontend code and backend code to replace all instances of "COMPLETED" with "DONE" in the task status to ensure consistency for end users.
• As a user, I expect the task status to be 'DONE' both in the frontend and backend, ensuring that the information matches and is easy to understand
