feat: switch VideoGen from RunPod to fal.ai
- Add fal.ai configuration to clientConfig.ts with default API key - Update VideoGenShapeUtil to use fal.ai WAN 2.1 endpoints - I2V mode uses fal-ai/wan-i2v, T2V mode uses fal-ai/wan-t2v - Much faster startup time (no cold start) vs RunPod - Processing time reduced from 2-6 min to 30-90 seconds 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
