Match banner brand, print splash, optional crop, and demo seed (#6)

## Summary
- Rebrand public site, portal, and emails from Ecoprint orange to the PRINTFORGE banner palette (navy / cyan / lime).
- Replace the loading splash with a CSS 3D-print animation; product uploads get a default-on smart crop + background filter checkbox.
- Add `manage.py seed_demo` for client walkthroughs on dev/beta only (refuses prod).

Closes #5.

## Test plan
- [ ] Public pages and buttons are cyan/lime, not orange
- [ ] Splash shows a printer building a model (or a static print if reduced motion)
- [ ] Product edit: smart-crop checked by default; uncheck stores the original photo
- [ ] `uv run python manage.py seed_demo` fills shop, contacts, leads, orders, campaigns
- [ ] `DJANGO_ENV=prod` seed_demo exits with an error
