Task App: Duplication, Rotational Tasks, and Auto-save

Problem: Users cannot easily duplicate tasks or groups, making setup repetitive. There is no way to track intermittent 'rotational' tasks with dates and notes. Additionally, the lack of auto-save leads to significant data loss if a user navigates away before hitting 'continue'.

Proposed Solution: Add a 'duplicate' icon for tasks and groups, a 'rotational' toggle for tasks with fields for 'date performed' and 'next due date', and implement an auto-save function.
