Decor Sounds 0.7.9 beta

WoW sound browser: cleaner filename-derived labels, expanded common abbreviations and recognized location hints. Technical filenames and IDs now appear under Details. Names and location hints are explicitly labelled as inferred from filenames, not verified descriptions. Edit Library name before adding a sound; adding an existing sound updates its name while preserving its ID and playback mode. Saved names persist after reload and do not change house or zone assignments. Preview isolation from 0.7.8 remains in place. Studio remains 0.7.8.
