feat(canvas): add video-prompt node and enhance video generation support
- Introduced a new node type "video-prompt" for AI video generation, including its integration into the canvas command palette and node template picker. - Updated connection validation to allow connections from text nodes to video-prompt and from video-prompt to ai-video nodes. - Enhanced error handling and messaging for video generation failures, including specific cases for provider issues. - Added tests to validate new video-prompt functionality and connection policies. - Updated localization files to include new labels and prompts for video-prompt and ai-video nodes.
