feat(auto): page local-music folders instead of truncating at 50 [size:exception]

Folders over the 50-item cap now show a "Mas..." item that reveals the next page on tap, instead of silently dropping the rest. Paging slices the cheap raw list before building any MediaItem, so items beyond the requested page are never resolved (art, title) -- proven by a call-count test. Also swaps the raw SAF content:// URI shown in settings for a parsed, human-readable folder name with a localized fallback across all 13 locales. servicio_audio.dart is untouched; this stays entirely within the local-music tree/dispatch layer.
