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.
