Add Todoist tasks with completion checkboxes to Planning tab

Make Todoist tasks visible by integrating into Planning tab:

- Add todoist-tasks template to planning-tab.html
- Update HandlePlanning to fetch and pass Tasks data
- Pass empty Projects slice (quick add form won't show initially)
- Completion checkboxes now visible and functional

Tasks with checkboxes now appear on Planning tab above Trello boards.
Users can click checkboxes to complete tasks instantly.
