fix "caddy-frontend: Publish only active slaves from main partition"

Use safe JSON serialisation/deserialisation, as otherwise unusual
slave_references can lead to issues and also character case is not kept.

Also care about case of log access user, which was undetected since
slave_reference in tests were always lowercase.
