feat: add IsLark field to FeishuConfig to switch between Feishu and Lark domains (#1753)

* feat(feishu): add Lark (international) support via IsLark config field

Add IsLark field to FeishuConfig to switch between Feishu and Lark
domains. Also fix domain inconsistency where WS client defaulted to
LarkBaseUrl while HTTP client used FeishuBaseUrl.
