Workflow editor null/zero fixes

Both are type casting issues that I think can be avoided if we make our ToolParameters pydantic models.

Is this the same root issue as #9484?

If so, I'm glad for the workaround leveraging typing on the ToolParameter side, but as a heads up there are likely still other issues related to the nested encoded json. I only took a quick look with that PR and passed it off to @guerler -- maybe he has an idea if there's more of an issue here?

Yes, I put that in the commit description. I did a fairly deep dive into how we build the tool form parameter dict on the client side.

heads up there are likely still other issues related to the nested encoded json.

Yeah, for sure, it isn't even "native" json, it's just that the client casts all values to strings, which isn't optimal by a long shot. I really hope a more reasonable serialized format will fall out of vue-ifying the tool form parameters without much/any effort.
