fix(jans-config-api): review comments on `/api/v1/audit` endpoint

```
"08-08-2025 09:26:19.056 User:a0bb3a77-7162-4ed4-be7f-bf6a8ab23a2b added -configuser using client:admin-ui",
"08-08-2025 09:26:19.056 CustomUser [inum=null, mail=newuser1234@gluu.org, displayName=newuser1234, givenName=newuser1234]",
"08-08-2025 09:26:19.056 true"
```
1. "08-08-2025 09:26:19.056 true" --- What does 'true' signify here?
2. On changing SCIM configuration `/jans-config-api/scim/scim-confign` no audit log is generated
3. I think we also need implement audit - logging for admin-ui plugin

**Description:**

a. Create new Role using Admin UI. (/jans-config-api/admin-ui/adminUIRoles)

b. No audit log generated for this created request on checking the endpoint (https://admin-ui-test.gluu.org/jans-config-api/api/v1/audit?startIndex=0&limit=100&start_date=12-07-2025&end_date=15-08-2025)

4. And we need a way to pass `audit log comments` (maximum 512 characters) from admin-ui
