#634 Refactor JSON handling in JSHandler.cs

[drualcman]

Updated JSHandler<TItem> to improve JSON deserialization by introducing JsonSerializerOptions with custom settings and a new NullToDefaultIntConverter. Refactored methods to use JsonElement for JavaScript interop callbacks, enhancing robustness and flexibility in handling JSON data. Removed unnecessary using directives for cleaner code.

Hi,

Thank you for this, however I'm not sure this is is the best way to handle this is issue.
We have control of the source of the json and it feels like we should try to fix it there.

I will take a closer look at the issue and take it from there.

Hi @joadan

Thanks to have a look. Yes, if you can fix how JS send then no need to change nothing into c# code.

I am using in production and the issue is that, from JS some times send null values where is expecting a number, or send a string when expecting a number, then can't auto deserialize.

That's why, after have a look from c# side I can manage, this is the only way I found to fixed it. So I implement in all the methods, to do same kind of work and deserialization in all methods.

The issue I detected is onClick and onHover. But while I am cheking the code, I feel much better do same in all methods.

Thanks again, and waiting for your news.
