Add a "reset" button label and new "filename_format" + "filename_format_help" entries to multiple locale JSON files (ar, de, es, fr, hi, id, it, ja, pl, pt, ru, tr, zh). The help text documents supported yt-dlp output template variables (%(title)s, %(uploader)s, %(upload_date)s, %(resolution)s, %(id)s, %(ext)s) so the UI can accept a custom output filename format.
Standardize and simplify analysis/status strings across multiple language files by removing percent-based prefixes and verbose phrasing, adding concise messages with trailing ellipses. This updates localization for ar, de, es, fr, hi, id, it, ja, pl, pt, ru, tr, and zh (ytsage/languages/*.json) to make progress messages cleaner and consistent for both regular and ytdlp-related steps.
