docs: add consolidated dev URL reference and migrate /shop to /storefront

- Add Development URL Quick Reference section to url-routing overview
  with all login URLs, entry points, and full examples
- Replace /shop/ path segments with /storefront/ across 50 docs files
- Update file references: shop_pages.py → storefront_pages.py,
  templates/shop/ → templates/storefront/, api/v1/shop/ → api/v1/storefront/
- Preserve domain references (orion.shop) and /store/ staff dashboard paths
- Archive docs left unchanged (historical)
