fix: Resolve remaining compilation errors

- Fix ReminderReceiver: use Class.forName() to avoid Intent type shadowing
- Fix NoteWidgetProvider: use Class.forName() to avoid import conflicts
- Fix NoteQuickNoteWidget: use Class.forName() for EditorActivity
- Fix MainActivity: use ActivityResultContracts.GetContent("*/*") without manual Intent
- Remove unused Intent import from widgets
