fix(充值商品): 移除已退役的 bonus_points / duration_days 入参

- 后台 upsert 请求 DTO 与 SpacetimeDB procedure 入参移除 bonus_points、duration_days（评审第 19 条）
- 充点商品固定「¥1 = 10 泥点、无首充赠送」，module 落库统一写 0，保留退役列兼容存量 schema
- 删除 InvalidRechargeProductFields 校验与错误文案；api-server / spacetime-client 同步收敛
- admin-web 表单移除「首充赠送」输入与状态，列表改为只展示基础泥点
- scripts/admin-web-fake-api.mjs 假数据同步 bonusPoints: 0
