Unify namespace lifecycle wide event names (#11720)

## What changed?

- emit remote cluster and namespace replication lifecycle records under
`namespace_lifecycle`
- retain compatibility aliases for specialized event-name constants with
TODO cleanup
- update tests and shared envelope documentation

## Why?

Update schema event names to match namespace lifecycle schema which
currently exist so they are properly interpreted.

## How did you test it?
- [x] built
- [x] run locally and tested manually
- [ ] added new unit test(s)
- [ ] added new functional test(s)
