fix(activity): 移除对对碰候选奖励的库存前置过滤

对对碰结算时不再因 activity_reward_settings.quantity 小于等于 0 而提前跳过候选奖励，便于按实际商品库存进行排查与处理。

+# 📋 实施计划：扫雷排行榜管理后台 + 去除免费模式
+
+## 背景理解
+
+用户说明：
+1. **没有免费模式**：`minesweeper_free` 这个 game_type 已废弃，前后端都要移除
+2. **排行榜需要在管理后台展示**：当前排行榜只有 App 端接口，管理后台缺少排行榜 Tab
+3. **"积分"含义模糊**：排行榜里的 `total_rank_points` 字段是"游戏对战分"，不是平台积分（points），页面上要加说明
+
+---
+
+## 任务类型
+- [x] 全栈（后端 + 前端并行）
+
+---
+
+## 技术方案
+
+### 后端
+在 `internal/api/game/handler.go` 新增一个 Admin 专用排行榜接口：
+- `GET /api/admin/games/leaderboard` — 管理后台查排行榜（分页、支持搜索用户昵称）
+- `GET /api/admin/games/records` — 管理后台查每局对战记录（分页、支持按用户/时间筛选）
+
+两个接口都走读库，无需鉴权以外的特殊处理。
+
+### 前端
+在 `web/admin/src/views/operations/minesweeper/index.vue` 新增两个 Tab：
+- **排行榜 Tab**：表格展示所有玩家的排行数据，含"对战分"说明
+- **对战记录 Tab**：按局查每场游戏的明细
+
+同时去掉前端中所有 `minesweeper_free` 的相关逻辑和 `game_type` 切换选项。
+
+---
+
+## 实施步骤
+
+### Step 1 — 后端：新增 Admin 排行榜接口
+
+**文件**: `internal/api/game/handler.go`（在现有 Admin API 区域末尾追加）
+
+```go

+            "list":      rows,
+        })
+    }
+}
+```
+
+### Step 2 — 后端：注册新路由
+
+**文件**: `internal/router/router.go`
+
+在 admin 认证路由区域找到 game 相关路由，追加：
+```go
+adminAuthApiRouter.GET("/games/leaderboard", gameHandler.GetAdminLeaderboard())
+adminAuthApiRouter.GET("/games/records", gameHandler.GetAdminGameRecords())
+```
+
+### Step 3 — 后端：SettleGame 去掉免费模式分支
+
+**文件**: `internal/api/game/handler.go`
+
+`isFreeMode` 判断相关逻辑仍可保留（对 `minesweeper` 类型无影响），但移除文档/注释中所有 `minesweeper_free` 提及。
+实际上后端逻辑本身没问题，如果 Nakama 不再发送 `minesweeper_free` 类型就不会触发，无需修改业务逻辑。
+
+### Step 4 — 前端：在 index.vue 新增"排行榜"Tab
+
+**文件**: `web/admin/src/views/operations/minesweeper/index.vue`
+
+#### 4.1 在 `<el-tabs>` 中新增两个 Tab pane（追加在"配置预览"之前）
+
+```html
+<!-- 5. 排行榜 -->
+<el-tab-pane label="排行榜" name="leaderboard">
+  <div class="tab-content">
+    <el-alert

+```
+
+#### 4.2 在 `<script setup>` 中追加响应式数据和 API 函数
+
+```typescript
+import request from '@/utils/http'
+
+// 排行榜
+const lbSearch = ref('')
+const lbLoading = ref(false)
+const lbList = ref<any[]>([])
+const lbTotal = ref(0)
+const lbPage = ref(1)
+const lbPageSize = ref(20)
+
+const fetchLeaderboard = async () => {
+  lbLoading.value = true
+  try {
+    const res = await request.get('/admin/games/leaderboard', {
+      params: { page: lbPage.value, page_size: lbPageSize.value, nickname: lbSearch.value }
+    })
+    lbList.value = res.list || []
+    lbTotal.value = res.total || 0
+  } finally {
+    lbLoading.value = false
+  }
+}
+
+// 对战记录
+const recUserID = ref('')
+const recMatchID = ref('')
+const recLoading = ref(false)
+const recList = ref<any[]>([])
+const recTotal = ref(0)
+const recPage = ref(1)
+const recPageSize = ref(20)
+
+const fetchRecords = async () => {
+  recLoading.value = true
+  try {
+    const res = await request.get('/admin/games/records', {
+      params: {
+        page: recPage.value,
+        page_size: recPageSize.value,
+        user_id: recUserID.value || undefined,
+        match_id: recMatchID.value || undefined,
+      }
+    })
+    recList.value = res.list || []
+    recTotal.value = res.total || 0
+  } finally {
+    recLoading.value = false
+  }
+}
+```
+
+#### 4.3 在 `onMounted` 中追加调用
+
+```typescript
+onMounted(() => {
+  loadConfig()
+  fetchLeaderboard()
+  fetchRecords()
+})
+```
+
+#### 4.4 监听 Tab 切换（可选优化）
+
+在 Tab 切换到对应 Tab 时按需加载，避免首次全量请求：
+```typescript
+watch(activeTab, (val) => {
+  if (val === 'leaderboard') fetchLeaderboard()
+  if (val === 'records') fetchRecords()
+})
+```
+

+## 关键文件汇总
+
+| 文件 | 操作 | 说明 |
+|------|------|------|
+| `internal/api/game/handler.go` | 修改 | 新增 `GetAdminLeaderboard()` 和 `GetAdminGameRecords()` 两个函数 |
+| `internal/router/router.go` | 修改 | 注册两条新路由 |
+| `web/admin/src/views/operations/minesweeper/index.vue` | 修改 | 新增排行榜和对战记录两个 Tab + script 逻辑 |
+
+---
+
+## 注意事项
+
+- "积分"含义：页面上 `total_rank_points` 显示为"对战分"，并加 Alert 说明，避免与平台积分（points/兑换币）混淆
+- 不需要新建文件，全部在现有文件中追加
+- 后端无需修改任何免费模式的业务逻辑；前端 Tab 中不再展示 game_type 切换选项即可
+- `activeTab` 初始值改为 `'board'`（已经是），排行榜 Tab 不作为默认 Tab
+- 分页默认每页 20 条
+
+---
+
+## SESSION_ID
+- CODEX_SESSION: N/A（本次直接由 Claude 规划，无外部模型调用）
+- GEMINI_SESSION: N/A

+
+## 六、今日未发生的操作
+
+以下维度已查询，今日均**无记录**：
+
+- 直播间抽奖 (livestream_draw_logs) — 无
+- 抖音奖励发放 (douyin_reward_logs) — 无
+- 游戏票变动 (game_ticket_logs) — 无
+- 任务中心事件 (task_center_event_logs) — 无
+- 发货记录 (shipping_records) — 无
+- 退款记录 (lottery_refund_logs) — 无
+
+---
+
+## 七、待确认排查点
+
+1. **积分缺口 28,600 分**：用户今日积分消耗比赚取多 28,600 分，说明使用了历史余额。如果用户质疑积分不对，需对比历史 ledger 总收支是否与当前余额 0 一致。
+
+2. **抖音 reward_granted 95 次 vs 通行证使用**：抖音发放 95 次通行证，用户另外购买了 330 次（¥910），总计可用 425 次。实际抽奖消耗 325 次（通行证抽奖）+ 微信直付抽奖不消耗通行证。需确认通行证余量是否与账户记录匹配。
+
+3. **合成产出追踪**：156 次合成消耗了 400 个碎片，产出 156 个合成品。产出的 156 个合成品被批量兑换为积分（对应 batch_redeem 的 157 件 = 156 合成品 + 1 个 MG黄金百式）。

+4. **level1 大奖确认**：订单 42196 的第 8 抽(draw_index=8) 命中 level1，对应 MG黄金百式2.0 (product_id=547, ¥390)。可在 user_inventory 中确认 id=83933。
