council(execute): BackendArchitect - fix P0/P1 blocking issues in Phase 2

[P0] Fix plugin Base controller to extend ShopXO Common class:
  - Now extends Common instead of standalone class
  - Automatically gets IsLogin() + IsPower() + ViewInit()
  - All child controllers (SeatTemplate/Ticket/Verifier/Verification) inherit fix

[P1] Fix code bugs found during codebase analysis:
  - Verifier.php: column('nickname|username', 'id') → CONCAT SQL (syntax error)
  - SeatTemplate.php: countSeats() wrong logic (count × rows → per-row scan)
  - Ticket.php: verify() returned view on POST → always JSON
  - Ticket.php: detail() returned view on error → JSON
  - SeatTemplate.php: delete() returned view on POST → JSON, plus soft-delete

[P1] Fix verifyTicket() in TicketService:
  - Wrap in Db::transaction() for atomicity
  - Add SELECT ... FOR UPDATE pessimistic lock to prevent double-verify
  - Add try/catch with error logging

[P2] Fix export() memory issue:
  - Replace select() with cursor() to avoid OOM on large datasets

Also: update plan.md with Round 2 findings, claim Task B1/B2/B3/B5

+### 关键阻塞问题
+
+| # | 问题 | 严重度 | 影响范围 |
+|---|------|--------|---------|
+| 1 | plugin Base 控制器只做登录检查，未做权限检查 | **P0** | 所有插件后台页面 |
+| 2 | `Verifier.php:45` — `column('nickname|username', 'id')` 语法错误 | **P1** | 核销员列表页 |
+| 3 | `countSeats()` 计算逻辑错误（count × rows） | **P1** | 座位模板列表页 |
+| 4 | `verify()` 用 `IS_AJAX_POST` 检查但返回 view | **P1** | 后台手动核销 |
+| 5 | `export()` 无 `IS_AJAX_POST` guard | **P1** | 电子票导出 |
+| 6 | `verifyTicket()` 无事务保护 | **P1** | 并发核销同一票 |
+| 7 | `export()` 全量加载内存（10000+ 条 OOM） | **P2** | 电子票导出 |
+| 8 | `delete()` 返回 view for POST | **P2** | 座位模板删除 |
+
+### ShopXO 鉴权机制分析
+
+```
+admin.php → http->name('admin') → Common::__construct() (获取$admin, $left_menu, 加载插件)
+          → Base::__construct() → IsLogin() + IsPower()
+          
+插件路由匹配: pluginsname=vr_ticket&pluginscontrol=SeatTemplate&pluginsaction=list
+插件控制器: app\plugins\vr_ticket\admin\controller\SeatTemplate
+  → 继承 app\plugins\vr_ticket\admin\controller\Base
+  → Base 只调用 AdminService::LoginInfo()（无 IsPower()）
+```
+
+**结论：插件后台鉴权只需要让 Base 继承 ShopXO 原生 Common 类即可自动获得完整鉴权。**
