The castle LNbits extension was renamed to libra. Updates the
default-install / default-user env vars in docker-compose.dev.yml
and the fava-url pin in lnbits-entrypoint.sh (DB filename, slug,
log prefix, comments). The entrypoint script was previously
untracked — tracking it now so the rename persists for fresh
checkouts.
