FR : Archive functionality

[tu2-atmanand]

Instead of completely deleting the task, an archived state can be maintained.

For example, when the user will going to archive a task instead of completely deleting it. The task will be simply comment out, so it wont be visible in the Live editor as well as in Reading view. For example :

%% - [ ] Adding new simple task | 📅 2025-01-07 
	- [ ] This is a sub-task.
	This is a line in the task body. %%

Possible solution

• When user will click on the delete button, the Delete confirmation popup will open. In this same popup add a new button : Archive Instead
• When user will press this button, the task will be archived as above, instead of completely getting deleted.
