Source And Target Face Selection Ui With Preview

Unique: Integrates real-time face detection visualization directly in the browser using canvas rendering, allowing users to see and correct detection results before submitting to the backend. This reduces failed processing attempts and improves user confidence, differentiating from batch-only tools that provide no preview.

vs others: More user-friendly than command-line tools (DeepFaceLab) which require manual face detection setup, and more transparent than black-box APIs that process without showing what was detected
