The Songs library reset sort + filters to defaults on every visit; testers asked
it to remember their choice ("most players pick a preferred sort and leave it").
Persist sort, format, view, and the drawer filters to localStorage
('v3:songs-prefs'), restored once at first build. Cold start stays the neutral
Artist A-Z default. The search query and the artist/album drill-down are
deliberately NOT persisted (navigational). Single write point in reload() (where
every change already funnels); every restored value is validated against its
option list, so a removed/stale setting can never wedge the toolbar. Global (not
per-provider) for now.
