feat: 实施严格部门权限控制并修复导入功能

主要修改:
- 添加严格的部门层级权限控制（只看自己及下级部门，不看父级）
- 在 filter_permits_advanced() 添加 expand_department_family 参数
- 修复许可导入时的部门自动绑定功能
- 在 API 端点添加用户认证和部门权限过滤

技术细节:
- lawrisk/api/v2.py: 添加 @login_required 和部门权限过滤逻辑
- lawrisk/services/licensing_repo.py: 添加 expand_department_family 参数控制部门扩展行为
- static/db_admin.html: 修复导入功能，自动绑定到用户部门
- lawrisk/api/auth.py: 添加 is_superuser 权限检查

影响范围:
- 用户现在只能看到自己部门及下级部门上传的许可事项
- 新导入的许可事项会自动绑定到当前用户的部门
- 超级管理员不受影响
