Fix missing settings button, disappeared events, and tab refresh bug

- Add settings gear icon link to dashboard header
- Fix GetTasksByDateRange/GetCardsByDateRange to include overdue items
  (changed from BETWEEN to <= end, filter completed tasks)
- Fix refresh replacing active tab with tasks tab by using
  htmx.trigger(body, 'refresh-tasks') instead of innerHTML+htmx.process
- Add refresh-tasks hx-trigger to meals, shopping, conditions tabs
- Add tests for overdue inclusion/exclusion, settings link, template data
