* added `ctx.v1.grants` to "complement tokens" flow
* document `ctx.v1.getUser()` in "complement tokens" flow

* feat(actions): add getUser() and grant

* map user grants

* map claims

* feat(actions): claims in complement token ctx

* docs(actions): add new fields of complement token

* docs(actions): additions to complement token

* docs(actions): correct field names
