replace per-app deploy scripts with generic deploy.sh

Dispatch now validates the command format and routes to a single
deploy.sh that handles any app. This fixes first-deploy failures
for new apps (dispatch no longer needs a static case list) and
simplifies new-app.sh (no deploy script or dispatch update needed).

Also adds input validation to new-app.sh, set -euo pipefail to
deploy scripts, and dnf module reset before nodejs install.
