[6.x] Fix collection whereStatus logic

[jackmcdade]

Closes #13341

---

Note

Medium Risk
Changes status-filtering query logic for dated collections, which can affect what entries appear as scheduled/expired in listings and badges. Risk is moderate due to potential behavior changes across collections with different date visibility settings.

Overview
Fixes whereStatus('scheduled'|'expired') filtering so dated collections only return results when their corresponding date behavior is private; collections with public or unlisted future/past behaviors now intentionally return no matches for those statuses.

Extends EntryQueryBuilderTest::it_filters_by_status with new news and alerts collections to validate status results when future or past date behavior is unlisted.
