feat(shared-triggers): emit shared events from group services (M2.3)

Browse Source 
ServiceEventEmitter gains emit_shared(cx, owning_group, event) (default no-op);
OutboxEventEmitter implements it — matches shared triggers on the owning group
and writes outbox rows stamped with the WRITER app_id (dispatch runs under the
writer). GroupKv/Docs/FilesServiceImpl gain an events field (Noop default +
with_events builder) and emit on set/create/update/delete; the host wires the
outbox emitter via with_events. Closes the "group trigger has no app to watch"
gap. Authoring + validation land in M2.4.
