Csse pyd2 model convert classes

[loriab]

Description

currently atop #349

• main Input/Result classes and FailedOperation gained a convert_v(<ver>) function to transform to other version. transformation trivial at this point b/c this is pydantic's purpose, but functions will differentiate at the rearrangement milestone. Needed to actually validate schema_version field so it would overwrite at conversion.
• added model_dump, model_dump_json, copy_model to v1 so easier to write code that can take both model types. Levi had done the reverse and added dict, json, copy to v2, but I'm thinking this is the better way. Haven't removed Levi's fns.
