后台充值订单实付口径、发放泥点列、用户累计充值与兑换码单位

- 新增 AdminRechargeOrderEntryPayload.paidAmountCents：只有 paid_at 存在的订单才有实付，未支付 / 已关闭 / 已过期固定为 0
- 充值管理列表把「金额 / 泥点」拆成「实付」「发放泥点」两列，未支付行实付显示「未支付」并附订单金额小字；退款面板「订单实付」改读同一字段
- 用户详情充值订单表新增「发放泥点」列，商品列只保留商品名，实付同样按 paidAmountCents 展示
- 用户详情新增 cumulativeRechargedCents：api-server 按 user_id 读取 profile_recharge_order，只累加 paid_at 存在的订单金额（退款不回减），单次上限 500 行，读取失败或命中上限返回 null
- 用户详情身份区新增「累计充值」，读不到时显示「未知」，不用用户详情最多 20 条订单在 BFF 或前端近似重算
- 兑换码奖励单位收口为泥点：输入标签与列表列头改「奖励泥点」，单元格带「泥点」单位，避免被当成元
- 新增后端 2 条累计充值口径单测与前端 2 条用例（未支付不显示实付且发放泥点独立成列、累计充值未知态）
- 同步后端架构数据契约（实付口径 / 累计充值来源与上限 / 兑换码奖励单位）与决策记录
- 验证：cargo check -p api-server；cargo test -p api-server --bin api-server admin（138 passed / 0 failed / 1 ignored）；npm run admin-web:typecheck；npx vitest run apps/admin-web/src（220 passed）；cargo fmt --all --check、check:encoding、check:doc-index、git diff --check 通过
