fix: add card_id to google_search and web_search_deep ui.push for precise matching

Each search result card now carries a unique card_id containing the tool call id
(e.g. google-search-<tc.id>), enabling the ToolCallStatus exact-match logic to
correctly bind cards to their originating tool call without index-based offset errors.
