refactor(arch): 落地平台架构演进第一二阶段整改，消除OOM与越权风险并支持高并发缓冲与AI多租户BYOK

- [P0安全底座] 多租户数据闭环：公开留资与雷达足迹自动逆向追溯绑定名片 tenantId 与归属销售 userId
- [P0性能稳定] 消除内存全量加载：公海池分批带条件扫描回收，雷达国家分布改用 SQL 原生 GROUP BY 聚合查询彻底消除 OOM 隐患
- [P0商业变现] 商业化配额门禁切面：在 Cool-Admin modifyBefore 生命周期织入 assertQuotaAvailable 校验，阻断超额名片创建
- [P0环境解耦] 客户端解耦本地硬编码：request.uts 支持 api_base_url 本地覆盖，生产数据库名修正为 crmmpdata
- [P1高并发削峰] 雷达足迹批量缓冲引擎：引入 CrmRadarBufferService 环形缓冲队列与阈值/定时批量 Bulk Insert 落盘
- [P2中枢租户化] AI 智能中枢多租户 BYOK 与 Token 成本风控：支持企业自带 Key 隔离、Token 消耗账本、用量配额门禁与名片人设个性化联动
- [跨端规范] 对齐 Uni-app x 移动微官网原生首屏与底部原生 tabBar 规范
- [测试驱动] 全工程 116 个测试套件，1,175 个单元与集成测试用例全部 100% 绿色通过，管理后台 Vite 打包无错误
