Enhance task management with start dates and improved visibility

Introduce task start dates, allowing for future task scheduling and better visibility for managers and employees. Admins can now see all tasks, while other roles only see tasks that have started or have no start date. Includes UI updates to visually distinguish future tasks and a new form for creating tasks with start and due dates.
