Add deploy-instance.sh: spin up isolated lchat instances from one config

Templates a throwaway per-instance app.toml (unique app name + disk name) in a
temp dir and deploys via 'miren deploy -d'. No per-instance config in git; no
secrets in the script (admin token is generated or passed at runtime).
