fix(frontend): resolve 4 P2 architecture issues (Wave 3)

FRONT-I-01: Extract Auth components to Razor Class Library packages/blazor-ui/
- Created GoodGo.BlazorUi RCL (net10.0, MudBlazor 8.15) at packages/blazor-ui/
- Moved AuthButton, AuthCard, AuthInput, OtpInput, BrandPanel, SocialLogin, LanguageSwitcher
- Referenced RCL from WebClientTpos.Client via ProjectReference
- Added GoodGo.BlazorUi.Components.Auth/Common namespaces to _Imports.razor

FRONT-I-02: Add ARIA/accessibility attributes (WCAG 2.1 AA)
- AuthButton: aria-label, aria-busy, aria-disabled, aria-hidden on decorative icons
- OtpInput: role=group, aria-label per digit, autocomplete=one-time-code
- PosLayout: aria-expanded + aria-controls on sidebar/order toggles, aria-label on all icon buttons

FRONT-I-03: Implement Style Dictionary design token pipeline
- Created packages/design-tokens/ with token JSON (color, spacing, typography, border)
- Style Dictionary config outputs: CSS custom properties → wwwroot/css/tokens.generated.css
- Second output: C# constants → packages/blazor-ui/DesignTokens/DesignTokens.g.cs
- Added tokens:build script to root package.json
- Added tokens.generated.css link to index.html (before app.css for cascade correctness)

FRONT-I-04: Replace eval() in OtpInput with safe JS interop
- Created wwwroot/js/otp-input.js with window.focusOtpInput(index) helper
- Replaced JS.InvokeVoidAsync("eval", ...) with JS.InvokeVoidAsync("focusOtpInput", index)
- Eliminates CSP-violating eval(), improves security and debuggability
