Obfuscated IDs do not work in atomic operations

[bart-degreed]

Obfuscated IDs cannot be used with an atomic:operations request, because the deserializer attempts to convert the incoming id JSON element value to TId, bypassing any custom obfuscation logic. Instead, it should assign IIdentifiable.StringId, without performing this validation upfront.
