Skip --impersonate flag when using bundled yt-dlp

Browse source 
The bundled PyInstaller binary doesn't include curl_cffi, so passing
--impersonate Chrome-146:Macos-26 makes it error out with
"Impersonate target ... is not available". System yt-dlp installed via
pip can have curl_cffi alongside it and works fine.

Centralize the decision in `Downloader::apply_impersonation` and apply
the same gate to the `/api/preview` handler.
