Subject: [PATCH] refactor: Update Application handlers to convert byte[] to
 Stream
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- ValidatePdfQueryHandler: Convert byte[] → MemoryStream before calling IPdfProcessor
- ValidatePdfAQueryHandler: Same pattern
- Update AutoMapper namespace imports (remove Domain.Models.ValueObjects references)
