FIX: Saving an edit on a reply can fail after expanding replies (#39919)
Editing a post that's a reply produced a "The requested URL or resource
could not be found" dialog when the post had been viewed via its
parent's expanded replies list. The dialog came from a `PUT
/post_replies/:id` request that 404s; the URL should be `PUT
/posts/:id`.

`loadMoreReplies` calls `store.find("post-reply", …)` then
`store.createRecord("post", reply)` on each result. The first stamps
`__type = "post-reply"` (and `__munge`, `__state`) onto each model. The
second re-hydrates the same `id` under `post` — and the topic stream's
canonical post for that `id` is already in the store. `_hydrate`'s
"update existing" path copies those internal fields onto the canonical
record via `setProperties`, so a later `post.save()` builds its URL from
the wrong `__type`.

Fix: skip every `__`-prefixed key when diffing in `_hydrate`'s update
path. Internal store/RestModel metadata stamped at hydration time has no
business being carried across types. The `__` prefix is the existing
convention for "internal", so future additions are protected by the same
guard.
