fix(dev): support root bind mounts and LAN Vite access

Keep the dev container as root for s6 init so composer can create
vendor/ on root-owned mounts, then chown writable paths to www-data.
Move init-setup into a shell script and expose VITE_HOST/PORT for
remote HMR (LAN/Tailscale) with Vite listening on 0.0.0.0.
