feat: cookies-from-browser per bypass HTTP 403 YouTube (v1.10.1)

Alcuni video YouTube restituiscono 403 anche con yt-dlp aggiornato.
Fix: nuova opzione Impostazioni "Cookies da browser" con dropdown
(chrome/safari/firefox/edge/brave). Priorita': file cookies.txt
esistente -> --cookies-from-browser <name> -> nessuno.

Bonus:
- core/paths.py::_bundle_dirs() ora include <project>/bundle_bin/
  anche in dev, cosi' python main.py usa lo stesso yt-dlp del build
  invece di Homebrew (spesso obsoleto)
- Helper _cookie_args() in downloader.py per non ripetere la logica
  su tutti i punti dove serve --cookies
