Studio UI test: recover from voice-picker renderer crash, scoped to macOS runners

Browse source 
Downgrades a headless-Chromium renderer crash in the voice model-picker step to a warning plus page recovery on macos-14, where CheckMediaAccessPermission can kill the tab. Linux and Windows strict smoke jobs keep hard crash coverage and any live-page failure stays a hard fail.
