Slice 4 of the on-box UI uplevel. The landing page is now the peak-end
first impression after install: welcome + hostname chip, a "Your apps"
tile grid consuming /api/apps (with the real icon and an app-specific
primary action — fileshare gets smb://<host>.local/files, everything
else falls back to Manage →), the existing system-status tiles kept
intact, and a subtle "Coming next" row of text-only links that jump to
the planned-features section on furtka.org. No dead tiles.
The status script now also writes ip_primary, kernel, ram_total and a
furtka_version read from /etc/furtka/version (TODO: pin that file at
install time; for now it reports "dev"). The settings page will
consume those in slice 5.
