REST API: Create comment should return comment ID after successful creation
When using the Checkmk REST API to create a comment for a host or service via:
- POST /cmk/check_mk/api/1.0/domain-types/comment/collections/host
- POST /cmk/check_mk/api/1.0/domain-types/comment/collections/service
the API responds with HTTP 204 No Content, returning no data about the created comment.
Problem
While the comment is successfully created, the lack of a response makes it difficult to interact with the comment afterward. There's no way to get the id or other metadata without a separate query, which adds complexity and fragility to automated workflows.
Proposal
Return the full comment object upon creation, matching the existing comment structure.
