 * Settings page e2e tests.
 *
 * These tests exercise two of the four Phase 3.7 config rows end-to-end:
 *   - payment_session_timeout_minutes (number input)
 *   - extension_default_action_on_timeout (radio)
 *
 * Strategy:
 *   1. Snapshot the current backend value before each test
 *   2. Mutate via the UI
 *   3. Reload to confirm persistence (rules out optimistic-only state)
 *   4. Restore the original value in afterEach (so the suite is rerunnable)
