test: add E2E Playwright tests for Node Library V2 sidebar

Add browser tests for the V2 Node Library sidebar tab gated by
Comfy.NodeLibrary.NewDesign feature flag. Tests cover tab visibility,
tab switching, folder expansion, and search filtering.

Also adds NodeLibrarySidebarTabV2 fixture class and exposes it via
ComfyPage.menu.nodeLibraryTabV2 for V2-specific locators.
