feat: migrate all remaining modules from rainyun-go-sdk

- domain(24), product(8), rbm(10), rca(21), rgs(38), ros(19),
  ssl(5), user(10), workorder(11), public remaining 5
- split nested response structs into reusable named types
- rgs reuses rcs request/response types
- fix source bugs: malformed paths, resp vs &resp, missing bodies
- register all 11 services in sdk.New
