Move events back into interface-class source files (restore #3975 placement)
Reverses the earlier dedup-by-re-export: event TYPE definitions now live in the
interface classes, and the emptied decomposed event files are removed.

- MessageSeenEvent            -> logos_delivery/api/kernel_api.nim
- Message{Sent,Error,Propagated,Received}Event -> api/messaging_client_api.nim
- ChannelMessage{Received,Sent,Error}Event     -> api/reliable_channel_manager_api.nim
- EventConnectionStatusChange -> api/logos_delivery_api.nim

Deleted (became empty after the move):
- logos_delivery/waku/api/events/message_events.nim
- logos_delivery/messaging/api/events.nim
- logos_delivery/channels/api/events.nim
health_events.nim keeps its two remaining events (content/shard topic health).

Rewiring: each layer re-exports its interface module (waku->kernel_api,
messaging_client->messaging_client_api, reliable_channel->reliable_channel_manager_api,
which also re-exports messaging_client_api). Deep emitters/listeners
(subscription_manager, waku_node, waku_node/relay, node_health_monitor,
recv_service, send_service) import the owning interface module directly.
kernel_api stays below node level (types/topics/message/store-common) so the
node->kernel_api imports are acyclic. liblogosdelivery builds.
