backup-slpmodularcms-db.sh named the CMS; this backs up slpsoftware
specifically, same as every other instance-scoped path already does.
Hardcoded in deploy-scp.yaml itself, so this is the actual pipeline
code, not just docs describing it.
deploy-scp.yaml: download, back up the production database before
touching anything, upload into a timestamped release, symlink the
persistent website in, switch current and restart, verify /health
with retries, prune old releases only once that check passes. No
sudo, no container actions, one shared interface U5 will call next.
