Fresh installs now redirect to /users/register instead of showing the
demo shop. Post-login redirect goes to /admin dashboard (with setup
checklist) instead of /admin/settings. Added 16 provider tests covering
index (list, delete, sync) and form (new, edit, test connection).

Consolidates admin_live/, theme_live/, provider_live/ into admin/
(with theme/ and providers/ subdirs). Renames shop_live/ to shop/
and user_live/ to auth/. Updates all module names, router refs,
test files, CSS source paths, and dialyzer ignore.
