json: improve error message for duplicate property

json: Implement Body.Content
...
This is a wrapper around Body.PartialContent that generates additional
error diagnostics if any object properties are left over after decoding,
helping the config author to catch typos that would otherwise have caused
a property to be silently ignored.
