fix deploy: only restart app services, never infra (postgres, rustfs)

Infrastructure services store state on disk. Restarting them via
docker compose causes unclean shutdowns that corrupt RustFS IAM.
Only restart the 5 application images that the pipeline builds:
notebooks, zotero, docs, api, mc.

Gitea, woodpecker, and other services pick up new .env values on
their next natural restart or can be restarted manually if needed.
