feat: improve login/logout flow in customer SPA

1. Logout flow:
   - Added confirmation dialog (window.confirm)
   - Changed to API-based logout (/auth/logout)
   - Full page reload after logout to clear cookies
   - Added loading state during logout

2. Login flow (already correct):
   - Uses window.location.href for full page redirect
   - Redirects to /store/#/my-account after login
