fix(frontend): route every user-center points label through the custom currency name

后台「积分配置 → 自定义货币名称」改名后，用户中心仍有大量硬编码
「积分」：做任务赚积分 / 购买积分 / 签到领积分、积分记录 / 积分任务、
每日可免费获取 XX 积分、我的积分、积分+1、创作中心积分收益等。

get_currency_name() 早已存在且可用，问题只是这些文案没有走它。
本PR 全部替换，无双路、无迁移：

服务端渲染（用户中心 renderers）
- credits-balance.php：购买/做任务赚/签到领 + 整个购买弹窗
- profile-credits.php：积分记录 / 积分任务 页签
- credits-points-tasks.php：每日上限三态与空态
- sidebar-creator.php / profile-creator.php：积分收益
- transfer-modal.php：积分转账提示
- Signin.php：签到详情弹窗（我的积分 / 奖励 tooltip / 积分+N）
- VipServiceModal.php：我的积分 / 积分兑换会员
- download-permission-card.php：购买价格

客户端渲染（JS 无法调用 PHP，注入 currencyName 到 aksrtData）
- signin.js：签到状态行「已签到 N 天 +1」
- credits.js：转账标题/金额标签 + 购买提示 toast
- cms-download.js：积分不足视图、我的积分 入口、余额不足文案
- pay-vip.js：积分兑换会员入口（优先 catalog.currency_name）
- order-center.js：订单行单位回退

契约测试同步改为断言模板构造而非死字符串，并新增两例：
改名后跟随、未注入时回退「积分」。
