Add task trash

[emptybutton]

For each task, need to make a button, after which a task moves from its map to a special map called a trash can.
Each user must have his own this special map. The transition to this map should occur after clicking on the special icon in the lower right corner of the screen. A separate task remains in the trash for 6 hours, after which it must be deleted. For greater performance and without setting up a huge number of timers, when you try to get an overdue task from the trash (which has been there for more than 6 hours), it should be deleted. In the trash, a task has an additional button to return from the trash back to the map from which it was deleted. When returning and returning to the trash, the timer should not be saved. When you try to click on the button to send a task to the trash in the trash itself, the task should be deleted without waiting 6 hours. When moving a task in and out of the trash bin, the task must maintain the coordinates of its position.
