MessagingClient sat one layer below where the documented layering
(Waku <- MessagingClient <- ReliableChannelManager) places it: it took a
raw WakuNode and reached around the Waku kernel to its internals. Make the
messaging layer hold the Waku kernel and read `waku.node` from there, so the
declared dependency matches the layering and the layer holds the kernel handle
it will later route through.
The health-monitor test hand-builds a WakuNode, so it now wraps it in a
minimal Waku (conf/stateInfo only satisfy {.requiresInit.}; the messaging
path reads neither).
