TEMP: enable notification/SSE flags across all UI test workflows

Flip enable_notification_system, enable_sse_history_updates, and
enable_sse_entry_point_updates in the Selenium, Playwright, and
Integration Selenium workflows so the full UI test surface exercises
the SSE pipeline. Revert before merging.
