Add useClipSkip parameter and None option for dimensions in image inference

- Added useClipSkip boolean parameter to conditionally include clipSkip in API request
- Added None option to dimensions dropdown to let model determine dimensions automatically
- When None is selected, width and height parameters are not sent to API
- This resolves compatibility issues with models that don't support custom dimensions
