feat: Turnstile captcha, menu khách + nút tắt topbar cấu hình từ admin, ẩn setting nhạy cảm

- Turnstile (App\Support\Turnstile, middleware turnstile) cho login admin và login/register/forgot/reset của khách; cấu hình ở setting key=turnstile, secret mã hoá SignRSA.
- Menu sidebar khách (setting client_menu) và nút tắt topbar (setting client_quick_links) do admin sửa qua administrator/client-menu[/quick-links], khách đọc v1/setting/menu, v1/setting/quick-links.
- v1/setting và settings/public chỉ trả whitelist PublicSetting::FIELDS (trước đây lộ bot_token, inet_api_key).
- Cài đặt tài khoản khách (preferences), rate limit theo IP cho register/resend-verify.
