Moves the deploy script off the server and into the repo as
scripts/update-app.sh, with the two fixes made during the v1.114.0 deploy:
- set -euo pipefail, so a failed git pull aborts instead of rebuilding and
restarting PM2 on unchanged code while printing "Update Complete"
- npm ci instead of npm install, which rewrote package-lock.json and left the
tree dirty so the next git pull aborted
The body is wrapped in a main() function because the script lives inside the
checkout it updates, and git pull rewriting it mid-run would leave bash
reading from a stale file offset.
