Obsidian 1.9.3 update: new Cards view, improved metadata editing & CSS fixes

Obsidian 1.9.3 Desktop now displays invalid cssclasses, aliases, and tags directly in Bases and the property editor, with options to fix them using the Format converter plugin. The update adds a new cards view layout in Bases, allowing files to be displayed in a grid with optional cover images. The property editor is now accessible inside page preview and Canvas, streamlining metadata editing across views.
