Update Spanish and Hindi translations

Improve localization by updating translations in ytsage/languages/es.json and ytsage/languages/hi.json. Spanish fixes provide full translations for interface help text, restart notice, playlist/save labels, dialog placeholders, and playlist save messages. Hindi adds translated strings for concurrent connections, related help text, and default selection settings for video quality and subtitles.
