Show Creation Date and Completion Date in Task Details

I would like task details to display both the creation date and the completion date (when applicable).

Currently, the only way to see when a task was completed is by navigating to the Completed tasks view. This makes it difficult to review the history of a task without leaving its detail page.

• Show Created on for all tasks.

• Show Completed on for completed tasks.

• Display these dates directly in the task details screen alongside other task metadata.
