Phase 2/3 完成：修复 Shiro javax/jakarta 兼容性，实现 US1 认证模块

修复：
- TokenFilter 改继承 OncePerRequestFilter（jakarta.servlet），
  移除 PathMatchingFilter（javax.servlet）依赖，解决 Lombok 级联失败
- ShiroConfig 用 FilterRegistrationBean 替代 ShiroFilterFactoryBean，
  避免 javax/jakarta Filter 类型不兼容；securityManager 调用
  SecurityUtils.setSecurityManager() 确保 @RequiresRoles AOP 可用
- LabelBackendApplication 排除 ShiroWeb 自动配置（WebAutoConfiguration、
  WebFilterConfiguration、WebMvcAutoConfiguration）
- SysUserMapper @InterceptorIgnore 修正为 mybatis-plus 包路径

新增（Phase 2 尾声）：
- SysCompany / SysCompanyMapper
- SysUser / SysUserMapper
- ShiroFilterIntegrationTest（无 Token→401、过期→401、角色不足→403、满足→200）

新增（Phase 3 / US1）：
- LoginRequest / LoginResponse / UserInfoResponse DTO
- AuthService（login + logout + me；BCrypt 校验；Redis Hash 存 Token）
- AuthController（POST /api/auth/login、POST /logout、GET /me）
- AuthIntegrationTest（正确密码→token、错误密码→401、退出后→401）
