fix(web): forward provider view props and listen for standard transitions

[OskarEichler]

Summary

• Forward View props through both web and compatibility SafeAreaProvider implementations. Props such as testID and onLayout are declared but currently dropped.
• Detect the standard transition property and use the correct transitionend event, before legacy prefixes. The existing Transition/transitionEnd pair never identifies standard CSS transitions, leaving env() inset changes unreported in standard-only environments.

No API or native implementation changes. Previously dropped View props now reach the backing View; standard inset transitions now trigger the existing measurement callback. Existing cleanup and prefixed fallbacks are retained.

Test Plan

• React Native 0.87.1 consumer: immutable install and lint, all 13 web production targets, all four browser-extension builds, and all four production-mode Metro bundles pass. 172 installed source/native/artifact files match the verified fork. Native implementation is unchanged; both products' Android/iOS Debug builds passed immediately before this JS-only batch.

• Existing Jest suite: 21 tests / four suites / 11 snapshots pass.

• TypeScript, ESLint (three existing deep-import warnings), targeted Prettier, CJS/ESM/declaration builds and whitespace checks pass.

• Actual source components with React 19/JSDOM: both providers forward testID/onLayout; a standard transition event updates insets exactly once; unmount removes the measurement element and resize listener. Baseline drops both providers' props and produces zero updates for that event.

• React Doctor: 86/100, only the existing compatibility-provider measurement-through-effect warning. No rule suppression.

• No test/spec files changed. Event/measurement checks use DOM mocks, not a real mobile browser/device notch.
