EdwardandDevBot NetBird 279adb8fdd [management] Return the reason when custom domain validation fails (#8122)
* [management] Return the reason when custom domain validation fails

The validate endpoint returned an empty 202 and ran the check in a
goroutine, so a failed verification only reached the management log.
Run the check in the request and return 204 or 412 with a classified
reason. Resolver errors are not forwarded.

* [management] Address review feedback on custom domain validation

Pass the request context to the lookup and store calls now that the
check runs in the request, compare the self-resolved name
case-insensitively, document the 412 like the other entries, and
check the returned error in the existing tests.

* [management] Match custom domain CNAME targets case-insensitively

DNS names are case-insensitive, so a CNAME pointing at the cluster in
different casing should validate instead of failing as a mismatch.

* [management] Add validation timeout
