Fix WordList item format and structure

- Properly format WordList items with nested <Text><s><r>text</r></s></Text> structure
- Add Image and PartOfSpeech elements to match Grid 3 format
- Preserve xsi:nil attribute in WordList cells (don't remove it)
- Keep AutoContent/WordList ContentType intact

This allows Grid 3 to properly display WordList content in AutoContent cells.
