test(startup): isolate persisted geometry regression (#37)

- Issue #37: remove only the persisted main-window startup geometry path and restore the pre-1.4.0 window dimensions for an A/B package run.\n- Keep the application startup workaround disabled so the test isolates the 1.4.0 regression instead of masking it.\n\nRefs #37.
