Issue Description:
app-services-sdk-js contains a module for RHOSE (smart-events) product. This smart-events module is quite fresh and contanis some deficiencies preventing our team from using it.

Spotted deficiencies are:

1. (critical) APIErrorCodes unable to use them. If I follow usage [2], I get an attached error. If I import them from "service-accounts-sdk" then APIErrorCodes are found, but they do not contain members like ERROR_1 MGDOBR-1011
2. (minor) official SDK operations are prefixed in some 'duplicity' way, which makes reading code harder. We used `remove-operation-id-prefix` for generation [3]
3. (minor) some fields are optional in official SDK [4], while they are not in openapi [5]

Acceptance Criteria: At least the (critical) point form the description is fixed.
