- setup_manager: fall back to update_password if admin already exists
(installer bootstrap creates admin; wizard now updates rather than fails)
- install.sh: chown repo to SUDO_USER instead of pic user so the
invoking operator can run make update without git safe.directory errors
- test: update mock to also stub update_password when testing total auth failure

The installer runs as root and chowns /opt/pic to the pic user.
Any other user (roof, operator) running make update then hits
"detected dubious ownership". Fix: add /opt/pic to system-wide
git safe.directory after clone, and add same guard in make update.
