test(native): open a document before editor fixtures

The Home tab exposes an editor store without a mounted canvas or text editor. Open New design during fixture setup and await actual editor readiness before populating nodes or starting text input. Reuse already-open documents and keep WebDriver input assertions unchanged.

Full check passes. Native WebKit text input, fixture reuse and Settings checks pass (4 tests); Windows-only layer dragging skips on macOS. Upstream Tauri service bridge/teardown warnings remain; this does not claim IME or native clipboard coverage.
