chore(core,console): update error handling of testing custom JWT

[darcyYe]

Summary

update error handling of testing custom JWT:

1. add API request body error handling for custom JWT console when testing
2. update the custom JWT test API interface, which brings a more understandable error message (we reused zod error message formatter to compose the zod error message, previous interface is not easy to be understood by Logto user due to the nested zod variable path)
3. reorder the content of sample user context to align with the zod guard, so that clicking reset button of sample user context does not change the content in the code editor

Testing

Tested locally.

Before this change, the error only show error code without detailed error message, which is hard for debugging.
