Pull request overview

Adds a new DataGrid “Semantic Search” demo to the demos app, providing implementations for jQuery, React (TS), React (JS), Angular, and Vue that query a remote ASP.NET backend with semantic search parameters.

Changes:

• Introduces new demo pages (HTML entrypoints + app code) for each framework approach under apps/demos/Demos/DataGrid/SemanticSearch/.
• Implements a shared UX pattern across approaches: DataGrid with remote operations + virtual scrolling + search panel + “Similarity Factor” NumberBox in the toolbar.
• Wires the demo to https://js.devexpress.com/Demos/NetCore/api/DataGridSemanticSearch via devextreme-aspnet-data-nojquery.

• Toolbar items use css-class="align-bottom", but there’s no CSS rule for .align-bottom.dx-toolbar-item in this Vue demo, so the alignment tweak won’t apply. Add the missing rule (same as the React variants).
