Enhance PDF viewer with annotations and WebAssembly

Added support for advanced annotation tools, including signature and stamp management, along with accessibility improvements. Introduced WebAssembly binaries (`qcms_bg.wasm`, `quickjs-eval.wasm`, `openjpeg.wasm`, `jbig2.wasm`) for enhanced performance in color management, JavaScript execution, and image decoding.

Implemented a JavaScript fallback (`openjpeg_nowasm_fallback.js`) for environments without WebAssembly support. Updated `Details.cshtml` to include a PDF viewer popup and added a new Razor Page (`ViewPdf.cshtml`) for secure PDF file access. Registered `.mjs` MIME type in `Program.cs` for PDF.js compatibility.

Enhanced localization with translations for multiple languages in `viewer.ftl` and added new icons, dialogs, and accessibility features. Updated `DXApp.sln` to include a new project for template management. These changes improve functionality, modularity, and user experience.
