fix(ux): auth workflow fixes — customer login, dashboard, auth service, YARP ports

Phase 1 fixes:
- Fixed Customer Login route (/auth/login/customer now renders correctly)
- Fixed YARP proxy ports for all microservices
- Fixed login links across all auth pages (/login → /auth/login)
- Created AuthStateService for role-based portal redirects
- Dashboard loads real shop data from BFF API
- Reverted UseBlazorFrameworkFiles (breaks .NET 10 MapStaticAssets)
- Created Home.razor landing page and LoginSelect.razor (compiled in DLL,
  Blazor client routing needs investigation for / and /auth/login routes)

Verified working:
- Customer Login: phone/OTP with social login
- Staff Login: green theme with role hints
- Admin Login: blue theme with security warning
- Branch Login: orange theme with stats
- Registration: form + API via YARP proxy
- Store Onboarding: 5 types (Café/Nhà hàng/Karaoke/Spa/Bán lẻ)
