fix: mount PVC at /config to persist Chrome and app state across restarts

The jlesage/baseimage-gui sets XDG_CONFIG_HOME=/config/xdg/config at
runtime, so Chrome was writing its profile to /config/xdg/config/google-chrome
which lived on ephemeral storage. This caused Chrome to open as a fresh
install on every pod restart.

Changes:
- Mount the PVC at /config instead of /home (aligns with baseimage-gui convention)
- Move user home directory to /config/userdata (on the PVC)
- Add explicit --user-data-dir for Chrome pointing to PVC path
- Clean up Chrome crash lock files and patch Preferences on startup
  to prevent session/cookie loss after unclean pod shutdown
- Update all scripts (sshd, init-repo, cont-init) to use new paths
- Remove unnecessary cont-init-home.sh
