RavenDB-25135 Restore GetPageWithoutCache on the encrypted VoronStrea…

…m read path

Reverts the VoronStream / LowLevelTransaction part of #22574: the encrypted read path must not acquire pages through the page-locator-backed GetPage. A locator hit returns the decrypted EncryptionBuffer pointer without going through AcquirePagePointer (no Usages++), while VoronStream's paired TryReleasePage always does Usages--.

When two index readers in one read transaction reference the same decrypted page (cloned Lucene inputs over a .cfs compound file), the ref-count under-counts and the buffer is freed/zeroed while a reader still holds it -> AccessViolationException in BufferedIndexInput.ReadBytes while querying encrypted databases.

GetPageWithoutCache bypasses the locator so every acquire isref-counted. The PageLocator.Reset added in #22574 is kept. Adds a regression test.
