Write auto-subs only if selected; show count

Downloader: add detection for "Auto-generated" subtitle selection and only append --write-auto-subs when an auto-generated subtitle is explicitly chosen (prevents always enabling the flag when any subtitles are requested). GUI: update subtitle label to display the number of selected subtitles when >0, falling back to the zero-selected message otherwise. Small UX and behavior fixes in DownloadThread and AnalysisMixin.
