Add missing obituary and affiliations fields, convert empty string
collection fields to empty arrays, and standardize field ordering
across all 44 modified person files to match _template.json
The commit adds a new image file named "Nolan_Berry.PNG" to the images
directory. The image file is associated with the person "Nolan Berry" in
the nolanberry.json file by updating the "mainimage" property with the
correct image path. This ensures that the correct image is displayed for
Nolan Berry in the application.
