feat(demo): redesign Blazor app with cloud drive UI and Tailwind CSS

Completely overhaul the demo Blazor application with a modern cloud storage
interface inspired by popular file hosting services. Add Tailwind CSS for
styling, new component architecture with file browser, preview panels, and
toast notifications. Include services for recent files, recycle bin, and
file icons. Also add Nuke build configuration and dotnet tools manifest.
