Rename 'Events' to 'Tasks' in NostrFeed to avoid confusion with Events module

Changed terminology in the scheduled events section of NostrFeed to use "Tasks" instead of "Events" to prevent confusion with the Events module (which handles event ticketing).

**Changes:**
- "Today's Events" → "Today's Tasks"
- "Yesterday's Events" → "Yesterday's Tasks"
- "Tomorrow's Events" → "Tomorrow's Tasks"
- "Events for Mon, Jan 15" → "Tasks for Mon, Jan 15"
- Updated comments: "Scheduled Events" → "Scheduled Tasks"

**Rationale:**
- **NostrFeed scheduled items** = Daily tasks and announcements (NIP-52 calendar events)
- **Events module** = Event ticketing system (concerts, conferences, etc.)
- Using "Tasks" makes it clear these are to-do items, not ticketed events

Empty state message already correctly used "tasks" terminology and remains unchanged.
