fix: set app user shell to /bin/bash so VSCode terminals work

baseimage-gui creates the app user (UID 1000) at runtime with
shell=/sbin/nologin and home=/dev/null. VSCode tries to spawn the
user's login shell for terminals, which fails with exit code 1.

Adds a cont-init script that runs as root after baseimage-gui's
adduser step and corrects both the shell and home directory.
