ss58 Prefix of 9072 not rendering in metadata

[mgravitt]

Hashed Network should have an ss58 address prefix of 9072. This format ensures that each address starts with ha.

For example, this is the same account with different prefixes:
42 prefix: 5CMhinFmhCkybhc1QNH4m7W8nc43PYvmi9mGBE6VDgSxk15r
9072 prefix: haWofjdKbfRECxmjLqwHJVPEFrD1SdeMo2FQeqHQZzXdm5ZmV

In our chain spec, it is set like this:

	properties.insert("ss58Format".into(), 9072.into());
	properties.insert("prefix".into(), 9072.into());
