Event names are local now, in the manifests and in the code

Every module named its events the way the old bus spelled a routing key —
`module.<module>.<verb>`. Design 29 says a module names an event locally and the
mesh works out where it lands, so all 37 were stale against a rule already
decided. On the new bus that derives into a namespace belonging to a module
called "module", so no cross-module subscription in the mesh matched anything:
nothing failed, nothing reacted (novox/hq 04-ISSUES/127).

36 manifests converted, and 43 files of module code with them. The code mattered
as much as the manifests: the runtime builds the subject from what `emit()` is
handed, so a converted manifest with unconverted code would have had the
permission and the subject disagree.

Three things the new check found on the way:

- `photos` emitted an event its manifest never declared, which the new bus refuses
  outright. Declared.
- `showcase` waited for an event nothing emits, so its demo could never be
  triggered — only `showcase` may publish under its own name. It emits both halves
  now.
- `distribution` declared an event named after a different module. It emits
  `image.pushed` under its own name. An event about a *role* belongs on the seat,
  where the name outlives whoever holds it, but the sdk has no way to publish on a
  seat yet, so that stays recorded rather than declared.

The audit logger's "everything" pattern is `**` rather than the old bus's `#`.
