fix(reminders): clear scheduled time when adding to today from dialog

When user clicks "Add to Today" in the reminder dialog, the task's
scheduled time is now always cleared, even if it was originally
scheduled for a specific time today (e.g., "2:30 PM today").

This ensures tasks become "sometime today" without a specific hour
when added from the reminder dialog, while preserving the existing
behavior for other flows (context menu, drag-drop).

- Add isClearScheduledTime parameter to planTasksForToday action
- Update reminder dialog to pass isClearScheduledTime: true
- Update meta-reducer logic to clear dueWithTime when flag is set
