test(web): preserve toast announcement and focus semantics

Browse Source 
Recovery feedback must remain available without stealing keyboard focus. Cover existing error/warning and success/info live-region distinctions, atomic contextual text and retained focus through the public toast entry point. This protects accessibility behaviour without adding product scope; DOM assertions do not establish screen-reader acceptance.
