feat: 实现用户登录认证与权限控制系统

- 新增用户登录页面与API端点（/api/auth/login、/api/auth/logout、/api/auth/me）
- 引入基于密码哈希的认证机制，支持默认管理员账号登录
- 创建访问控制模块（lib/access-control.ts），实现基于角色的权限验证
- 在现有API端点中集成权限检查，限制非管理员用户只能访问其所属项目数据
- 更新应用布局，要求用户登录后才能访问主界面
- 扩展用户表结构，增加用户名和密码哈希字段
- 调整项目、KR、目标、会议记录等资源的查询逻辑，根据用户权限过滤数据
- 改进管理页面（指标、模板）的删除操作，使用确认对话框替代直接确认
- 优化“我的KR”页面，为管理员提供全员KR概览视图
- 修复.gitignore文件中的拼写错误（.trae → .travis）
- 添加数据库迁移脚本，支持任务直接关联项目、禁用RLS、添加求助字段等
- 配置Next.js以支持独立输出和子路径部署
