Remove orphan PBXBuildFile entries and duplicate libAdapter.a reference

- Drop three (null) PBXBuildFile entries (B891FDAA, CDA101AF, CDCA7FA1)
  and their references in IronSourceAdapterTests and LiftoffMonetizeAdapterTests
  build phases; all introduced by 84ee65d as a side-effect of Xcode auto-save.
- Drop redundant direct PBXFileReference + PBXBuildFile for libAdapter.a
  (7FF2757F / 7FF27580) in UnityAdapterTests; the existing cross-project
  PBXReferenceProxy to UnityAdapter.xcodeproj's AdapterWithoutValidationScript
  target (AD6E38922EA1664B / AD6E3B3A2EA16D3C) is the canonical pattern shared
  with PubMatic/Verve/etc.

Addresses Copilot review comments on PR #20.
