Fix App Store submission: replace manual IPA zip with proper gym export and Apple Distribution signing

[Copilot]

altool was rejecting the IPA with "not signed using an Apple submission certificate" because the Fastfile bypassed xcodebuild -exportArchive — the step that re-signs with the distribution cert and embeds the App Store provisioning profile — by manually zipping the .app from the archive.

Changes

• Remove manual IPA creation workaround — Drops the gym(skip_package_ipa: true) + FileUtils/zip block that produced an improperly signed IPA
• Proper gym export with explicit export_options — Forces method: "app-store" and signingStyle: "manual" in the ExportOptions plist, overriding Xcode 26's tendency to inject method: development; includes explicit provisioningProfiles mapping for both app and extension targets
• code_sign_identity: "iPhone Distribution" → "Apple Distribution" in both update_code_signing_settings calls to match what match appstore actually installs on Xcode 16+

gym(
  configuration: "Release",
  project: "Code.xcodeproj",
  scheme: "CodifyOne",
  output_name: "Code",
  output_directory: File.expand_path("..", __dir__),
  export_method: "app-store",
  export_options: {
    method: "app-store",
    signingStyle: "manual",
    provisioningProfiles: {
      DEVELOPER_APP_IDENTIFIER => "match AppStore #{DEVELOPER_APP_IDENTIFIER}",
      DEVELOPER_APP_EXTENSION_IDENTIFIER => "match AppStore #{DEVELOPER_APP_EXTENSION_IDENTIFIER}"
    }
  }
)
