* Fix Python RPC dataclass: keep canvas_json_schema required

quicktype emits the freeform 'canvas_json_schema' field as 'Any', and the
post-processor was adding '= None' to every bare ': Any' annotation. That
turned the synthesized root RPC dataclass field into a defaulted argument
followed by required fields (canvas_list, ...), which made Python raise
'non-default argument follows default argument' at import time and broke
every Python SDK test plus the scenario import checks.

Scope the post-processor so RPC definition fields keep their required Any
annotation, matching the rest of the registry.
