fix: remove core LogIndexService to fix CI snapshot resolution

LogIndexService in server-core imported LogEntry from cameleer3-common,
but the SNAPSHOT on the registry may not have it yet when the server CI
runs. Moved the dependency to server-app where both the controller and
OpenSearch implementation live.
