 - [ ] Confirm delete_task operation.
 	- For actions that require confirmation, show confirmation message on selected line (horizontally centered) saying "Press enter to delete/archive. Any other to cancel." and await on `getch` for a `\n`. On archiving action this should only occur if the task is active. Use red/black for confirmation message surrounded by diamonds. Implement this using a function `bool get_confirmation(const char *message)`.
