chore: move conf types to api/conf

* move MessagingClientConf to api/conf/messaging_conf
* move ReliableChannelManagerConf to new api/conf/channels_conf
* impl modules now import their conf module, not the reverse
* logos_delivery_conf uses channels_conf, not reliable_channel_manager
* cleanup import lists
