add cert command to deploy.sh, use deploy user for cert issuance

- deploy.sh: add cert-<domain> command for zero-downtime SSL issuance
- new-app.sh: SSH as deploy user with key from Bitwarden instead of personal user
- remove DEPLOY_USER/DEPLOY_HOST env var requirements
- update all docs to reflect new flow
