docs(changelog): leave the entry to the release commit

The text is unchanged and waits with the other release drafts; keeping it
in the branch made CHANGELOG.md collide with every release that shipped
while this waited.

-### Changed
-
-- **Readings pushed in with a measurement token are now marked as coming
-  from an external device**, instead of being recorded as if you had typed
-  them in by hand. They show a badge in the measurements list and can be
-  picked out with the source filter there, so months later you can still
-  tell which readings came off the scale and which are your own. You can
-  still correct one if a sensor sends something wrong — readings owned by a
-  connected provider stay read-only, because the number is the provider's,
-  but these come off your own hardware.
-
-  Readings pushed in before this change stay marked as manually entered.
-  There is no way to sort them out after the fact: nothing recorded which
-  ones arrived through a token, and that is the gap this closes. If you want
-  a clean split, the readings from here on will have it.
-
-  One thing to check if you push through the batch endpoint: a re-push of
-  entries you had already sent may land a second copy, because a reading's
-  identity now includes where it came from. Delete the older pair if you see
-  duplicates.
-
-- **A push must not claim a source of its own.** Saying where a reading came
-  from is the server's job now, so a payload that names one — Apple Health,
-  manual, anything — is refused with a 422 rather than quietly relabelled,
-  and you find out on the first call instead of discovering later that your
-  rows say something you did not ask for. **If your automation sends a
-  `source` field, drop it**; the example in the Home Assistant guide never
-  did, so a setup copied from there needs no change. Apple Health is the one
-  that would have done real damage: that label is half of how the iOS app
-  recognises its own rows, and a bridge borrowing it corrupts the phone's
-  sync instead of merely mislabelling a reading.
