[Partner Nodes] fix(KlingTextToVideoNode): validation error for "kling-v2-master" model

[bigcat88]

The model_name enum on KlingText2VideoRequest went stale and was missing kling-v2-master.
Replaced it with a plain string per our Partner-nodes convention (the widget already constrains the values)

📝 Walkthrough

Walkthrough

This PR removes a type wrapper from the text-to-video request construction in the Kling node. The execute_text2video function now passes model_name directly to the KlingText2VideoRequest payload instead of converting it via KlingVideoGenModelName(...). This is a single-line change affecting how the model name parameter is handled when building the request.
