Fix Happy Coder startup: use happy daemon start, create home dir

The npm package installs a binary named 'happy', not 'happy-coder'.
Use 'happy daemon start' to run it as a background service.

Also create $HOME on the PVC if it doesn't exist yet, which was
causing git config failures on fresh volumes.
