Bundle local UI assets

[AstroZer01]

Summary

• Bundle the WebView UI stylesheet, fonts, and icons locally; remove runtime Tailwind CDN, Google Fonts, and Material Symbols dependencies.
• Move the runtime UI from wwwroot to Steam Desktop Authenticator/ui; the packaged application now loads it from app/ui.
• Add Tailwind source/configuration, a pre-commit check, CI validation, and release-time regeneration so committed UI CSS stays current.
• Document reliable Windows release builds from Command Prompt and Visual Studio 2022.

Why

The desktop UI now works without external style or font requests. The committed ui/assets/css/app.css keeps ordinary .NET builds simple, while UI contributors can deliberately regenerate it after changing templates or Tailwind configuration.

Build behavior

• Normal .NET publishes do not require Node.js because the generated UI stylesheet is committed.
• After changing a UI template, tailwind.config.js, or ui/tailwind-input.css, run npm ci (once after cloning or lockfile changes) and npm run build:ui, then commit the generated stylesheet.

Validation

• npm run check:ui
• dotnet build SteamDesktopAuthenticator.sln -c Release --no-restore
• dotnet publish "Steam Desktop Authenticator\Steam Desktop Authenticator.csproj" -c Release -r win-x64 --self-contained false -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=false -p:PublishTrimmed=false -p:EnableCompressionInSingleFile=false -p:DebugSymbols=false -o publish\ASDA
• Verified the release package includes app/ui pages and assets, excludes app/wwwroot and tailwind-input.css, and contains the WebView loader and runtime dependencies.

In `@Steam` Desktop Authenticator/tailwind.config.js:
- Around line 17-38: Update the Tailwind colors configuration to define the
missing secondary-container and on-primary-container tokens used by the
bg-secondary-container/20 and selection:text-on-primary-container utilities,
then regenerate app.css so both selectors are emitted and preserve the intended
navigation and selection styling.
