fix(ui): document status shows changed after publishing specific locale (#15765)

### What?

When `localizeStatus` is enabled and `defaultLocalePublishOption` is set
to `active`, publishing a specific locale leaves the document status
showing "Changed" instead of "Published" until the page is refreshed.

### Why?

The `publishSpecificLocale` callback in `PublishButton` only called
`setHasPublishedDoc(true)` on success, but did not reset
`unpublishedVersionCount` or `mostRecentVersionIsAutosaved`. The
`Status` component uses `unpublishedVersionCount > 0 && hasPublishedDoc`
to render "Changed", so the stale count kept the status incorrect.

The `publish` (all locales) callback already handled this correctly,
`publishSpecificLocale` was just missing the same state resets.

### How?

Added `setUnpublishedVersionCount(0)` and
`setMostRecentVersionIsAutosaved(false)` to the `publishSpecificLocale`
success handler, matching what `publish` already does. Added an e2e test
that reproduces the issue.
