feat(distribution): 分站前台按独立商城呈现并支持首页文案自定义

分站前台原本对顾客暴露分销身份，且登录等页面写死了主站品牌，
与「一手独立商城」的定位不符；同时首页文案全部硬编码，站长无法按自己口径调整。

去分销身份（顾客可见处）：
- 头部品牌区、首页主视觉、移动端认证卡去掉「官方分销/官方分销认证/官方分销站」标识
- 会员徽标「分销专享」→「会员专享」，「所属商城」兜底「专属分销站/商城」→「官方商城」
- 订单页说明改为「当前为【X】商城，仅展示在本站产生的订单记录」，保留订单按站隔离的必要说明
- 无公告时的兜底跑马灯、轮播角标去掉分销措辞
- 清理随之失效的 pc-brand-badge / mobile-brand-badge 样式

品牌跟随站点配置（即可自定义）：
- PC/移动登录页、移动注册页、加桌面引导页的品牌改为 站点名称 + Logo（无 Logo 取站名首字），
  不再写死主站「大锤商行」；主站行为不变（新增 store getter brandMark：分站取站名首字，主站仍为「锤」）

首页文案可配置：
- 新增迁移 000076 与 distribution_sites.storefront_text_json
  （tagline 头部副标题 / hero_badge 主视觉徽标 / hero_desc 主视觉描述 / card_sub 移动端卡片副标题）
- 分销后台「品牌装修 → 首页文案」可编辑，占位提示即默认值，留空或整段清空回落内置默认
- 贯通 UpdateSiteBranding → 公开站点信息接口（含 Redis 缓存失效）→ 前台 store 逐字段合并默认值
- 装修预览同步展示站长填写的副标题与徽标

测试：
- 后端补装修字段写入/公开接口透出/清空回落断言
- 前端新增 storefrontText 单测（默认合并、覆盖、空白与非法类型回落）
