Display app/package version at the bottom of the side menu

[JoshuaVSherman]

Summary

• Bumped package.json version from 3.1.2 to 3.2.0 on the first commit.
• Injected pkg.version at build time in vite.config.ts via Vite's define option as __APP_VERSION__.
• Declared the global variable __APP_VERSION__ inside src/global.d.ts for clean TypeScript compilation.
• Added a style-wrapped version label showing v{__APP_VERSION__} at the bottom of both mobileMenu and navLinks in src/App/AppTemplate.tsx.
• Updated mobile .nav-list styling in src/styles/_mobile.scss with height: 100% to ensure correct absolute positioning of the version label on all screen widths.
• Updated Vitest unit test snapshots to reflect the new version label element.

Closes #204

How to test locally

1. Run the development server locally:

   npm run dev

2. Open the application in the browser at http://localhost:7777.
3. Open the side navigation menu (click the hamburger toggle if on mobile or view the sidebar if on desktop).
4. Verify that the version string v3.2.0 is clearly visible and neatly positioned at the bottom of the side menu.
5. Resize the window to verify that the version string is present and correctly styled on both desktop and mobile resolutions.
6. Verify that automated test suite passes:

   npm test
