The code generator writes Go files, and its templates still spelled the
old import paths, so a module generated after this migration did not
compile: the router it emits declares InitBusinessRouter with the v1
*GinJWTMiddleware while common.AuthInit now returns the v2 type.
Two of the paths moved rather than gaining a /v2 segment - the jwtauth
and response shims under sdk/pkg are gone in v2 - so this is not the
same rewrite the Go files got.
