feat: 全系统优化 — 并发控制 + 冗余清理 + 数据流修复 + 全面测试

核心修复:
- 状态机加 SELECT FOR UPDATE 行锁，消除并发竞态
- hss_md_staff 加 role 列，登录从数据库读取真实角色
- 申请重复校验排除自身，全流程 20 步闭环通过
- 派单 SQL 修复 + 支付状态机过渡 + 完成服务 plan_item_id 修复

并发控制新增:
- RedisLockService (SET NX PX + Lua 安全解锁)
- RateLimiterService (Redis 滑动窗口 + API 拦截器)
- TransactionIsolationConfig (SERIALIZABLE for 支付回调)
- MqttPublisher (异步队列 + JDK TCP 探测)
- ObjectStorageService (AWS SigV4 预签名, 纯 JDK)

冗余清理:
- 删除 6 个死代码文件 (~620 行)
- hutool-all → JDK MessageDigest, 去 MapStruct, 去 jsr310
- haversine 提取到 GeoUtil, count/round 提取到 JdbcUtil
- 创建 platform layout 组件

前端修复:
- 登录页移除角色选择器, 由后端 JWT 返回
- 移除 ClientOnly 包裹, 页面正常渲染
- SPA fallback Nginx 配置修复

Docker: 运行时镜像 eclipse-temurin:17-jre-jammy (缩小 ~300MB)
