refactor: make bounded recovery observation events replica-scoped

Carry replica-scoped addressing through bounded recovery planning and completion events so the core no longer depends on a volume-only observation seam. This preserves the current single-replica catch-up and rebuilding behavior while aligning the observation side with the replica-scoped command path.
