Use Xcode 26 and iOS 26 simulator in iOS CI

[shai-almog]

Motivation

• Pin the macOS build/test steps to Xcode 26 to ensure the CI uses the newer Xcode toolchain for xcodebuild and related tooling.
• Update the simulator runtime to iOS 26.0 so UI tests and screenshot jobs target the matching iOS SDK.

Description

• Set DEVELOPER_DIR to /Applications/Xcode_26.app/Contents/Developer in scripts/build-ios-app.sh so the build step uses Xcode 26.
• Set DEVELOPER_DIR to /Applications/Xcode_26.app/Contents/Developer in scripts/run-ios-ui-tests.sh so the test step uses the same Xcode instance.
• Update the GitHub Actions workflow IOS_SIM_DESTINATION to platform=iOS Simulator,name=iPhone 16 Pro,OS=26.0 in .github/workflows/scripts-ios.yml so the simulated device targets iOS 26.0.

Testing

• No automated tests were run for this change because it is a CI configuration update only.
