Refactor webcam capture to avoid re-initialization on tab switches, fixing slow loading, camera flashing, and UI freezes.
The webcam start/stop was tied to tab visibility, causing repeated re-initialization of the DirectShow graph and blocking the UI thread. This change keeps a single capture instance alive, toggling preview visibility and updating the preview window's owner handle in-place without costly teardown/rebuilds.
