Adds automated Maestro tests that verify the sandbox correctly blocks unauthorized HTTP and WebSocket connections while allowing approved domains. Moves TestDeeplinkHandler to features/e2e/ domain structure.
- Native module test: verifies NativeModules proxy blocks access from non-whitelisted files - WebView initial load test: loads blocked URL directly, asserts onError - WebView JS navigation test: loads allowed page, attempts JS navigation to blocked URL, verifies URL didn't change via postMessage - Simplified Maestro assertions to just check overall pass/fail
Points rainbow-scripts postinstall at the @janic/emit-close-on-blocked-ws branch of react-native-sandbox until those fixes are merged.
Security layer removed, native module test no longer applicable.
