PUT/POST /license ignores policyConditions

### Current Behavior

policyConditions contents are ignored, even though the OpenAPI spec shows that you can send them

### Steps to Reproduce

```
curl --fail-with-body --silent --show-error -H 'Authorization: Bearer ' http://localhost:8081/api/v1/policy -X PUT -H 'Content-Type: application/json' --data-binary @- <<< '{"name":"Vulnerability Policy","operator":"ANY","violationState":"FAIL","policyConditions":[{"operator":"IS","subject":"SEVERITY","value":"CRITICAL"},{"operator":"IS","subject":"SEVERITY","value":"HIGH"}],"global":true}'

{"name":"Vulnerability Policy","operator":"ANY","violationState":"FAIL","policyConditions":[],"projects":[],"tags":[],"uuid":"2a8feba0-86d4-4532-9600-e9a017cf2d81","includeChildren":false,"onlyLatestProjectVersion":false,"global":true}
```

### Expected Behavior

policyConditions contents are not ignored, and the specified conditions are added to the policy
