feat(qt): kiosk profile release hardening

Integrate the Kiosk profile hardening round: 12 dedicated Kiosk views plus
22 shared opt-in hosts, shared navigation history with Back/Forward, Albums
as the default library tab, native paged Local Library (artists/tracks),
lightweight MyQBZ grid and detail, Ephemeral lifecycle, bounded lists and
artwork sized to the physical frame, static skeletons, 64px transport bar,
Settings touch reflow and a persistent Immersive exit.

Desktop keeps its prior behavior: every shared component defaults to the
desktop path and only opts into Kiosk behavior through explicit properties
(origin-relative ScrollMemory, viewport-bounded artwork requests).

Regression coverage: kiosk navigation and artwork Node tests added to the
runtime gate, scroll-origin fixtures for fixed and grouped rows, i18n
strings for all eight locales.

Verified by 750 release tests, six QML audits, Kiosk smokes at 800x480 and
1280x800 and a Desktop A/B with seven pixel-identical captures.
