Deploy to Phoenix / deploy (push) Failing after 7s
Adds webapp-nginx.conf, systemd/currencicombo-orchestrator.service, and install-prune-cron.sh — all three referenced by main's existing install.sh / deploy script / webapp.service / README but missing from the4a1f69acommit. Byte-identical to PR #31 branchded7d24. Closes gap so CT 8604 can boot cleanly.
