fix: Frame images and API endpoint updates

- Added KlingAI 6@1 (KlingAI 2.5 Turbo Pro) to video models
- Fixed frame images to always use base64 data URIs (not UUIDs)
- Added convertTensor2IMGBase64Only function for consistent frame image handling
- Fixed videoInputsFrame to use correct 'inputImage' key
- Updated API endpoint from runware.dev to runware.ai
- Ensured both frameImages.py and videoInputsFrame.py use consistent format
