Fix saving model between chats

[AbdBarho]

You can see this bug on dev or staging if you try changing the model couple of times.

Somewhere within the mess of server side / client side rendering the model config gets overwritten.

[AbdBarho]

when we change presets, we use the function reset, which sets the isDirty to false, so we are not saving.

The isDirty check is require to avoid update on the first render which use the first model config from serverside, not the one from localstorage

[notmd]

We should pass keepDirty option when update the preset:

reset({ ...config, model_config_name: selectedModel }, {
     keepDirty: true,
});

I refactored it, I added keep dirty like you said, and switched to using Controller instead of register and it works now

@AbdBarho I just the pushed the change with correct fix by using getValues. Look like useWatch only update the value on the next render. The docs also recommend to use getValue to access latest value immediately https://react-hook-form.com/api/usewatch/. I gonna merge this since Dragan requested this, so he can work on the plugin feature.
