fix(tests): fix Mac search test flakiness with platform-specific paths

On Mac, use __toggleSearchForTest (direct event emit) to open/close
search bar — bypasses nested iframe focus issues that cause Ctrl+F
dispatch to not reach the iframe. On Windows/Linux, keep actual Ctrl+F
and Escape keypresses for real user workflow testing. Add
__toggleSearchForTest helper in bridge.js.
