fix(erpnext): run bench setup production as root, add nginx+supervisor

- bench setup production requires root (is_root check) - was failing as frappe user
- Add nginx and supervisor as apt dependencies for production setup
- Remove custom erpnext.service - bench manages gunicorn+workers via supervisor
- Port 8000 → 80 (nginx reverse proxy)
- Fix bench update in CT to run as frappe user with proper PATH
