  button styling

  - Show “Not enabled” for WeChat when status.wechat_login is false.
  - Refresh /api/status on PersonalSetting mount and persist via
  setStatusData to avoid stale flags, enabling binding after admin turns
  on OAuth.
  - Unify Telegram button styling with other providers; open a modal to
  render TelegramLoginButton for binding; align disabled “Not enabled” and
  “Bound” states.
  - Introduce isBound helper and reuse across providers (email/GitHub/OIDC/
  LinuxDO/WeChat) to simplify checks and prevent falsy-ID issues.
