feat(notify): materialise notification images

Notify resolves app_icon and image-path theme names, decodes image-data to
a PNG under the image directory, and re-publishes the entry with its
image path. The daemon advertises body-images, and removeImage refuses to
touch a path outside its own directory so a client's screenshot file is
never deleted.
