fix(apple): resolve App Store validation errors

- Info.plist: drop unused `fetch`/`processing` background modes (no
  BGTaskScheduler implementation exists, which they would require); keep
  remote-notification.
- Info.plist: set ITSAppUsesNonExemptEncryption=false — the app's standard
  end-to-end encryption qualifies for the mass-market export exemption, so no
  compliance code is required.
- project.yml: emit dwarf-with-dsym for Release so archive symbol upload works.

The remaining upload errors (NFC "NDEF is disallowed", Unsupported SDK) are
artifacts of building with a beta Xcode/SDK 27 and clear when archiving with a
release/RC Xcode; NFCNDEFReaderSession legitimately requires the NDEF format
entitlement, so it is kept as-is.
