All hardcoded references to the old IP-based registry replaced across
Rust backend, Vue frontend, shell scripts, Dockerfiles, CI, and docs.

ISO build no longer copies netavark from build host (Debian 13/GLIBC 2.41)
which broke container networking on Debian 12 targets. Rootfs already
installs netavark from Debian 12 repos — just configure the backend.
Install RPC now adopts existing containers (from first-boot) instead of
erroring on duplicates. Container scanner extracts real versions from
image tags and detects available updates against pinned versions.
Frontend shows update button with version info when updates are available.
