Updated: SPA <title>, PWA manifest name/short_name, iOS web-app title,
"Install"/"Pin to home screen" copy, HomeView empty state, all Twig page
titles (login/register/setup/token/help), and the share-notification
email header. Left alone: the firmware-broadcast SSID PictureFrame-XXXX
(coordinated firmware change needed) and internal code/comment refs.
