chore: 文档与 IDE 配置整理

- .kiro/specs/ → docs/specs/（41 个历史需求 spec 迁移，移除 .config.kiro）
- CLAUDE.md 三层拆分：根文件精简 + apps/backend/CLAUDE.md + .claude/commands/
- 新增 /spec-close、/pre-change 两个工作流命令
- DDL 基线刷新（从测试库重新导出 11 个文件，dws 35→38 表，biz 18→21 表）
- BD_Manual → BD_manual 命名统一（48 个文件）
- 修复 3 处文档与数据库不一致（auth.users.status 默认值、scheduled_tasks 字段、RLS 视图数）
- 新增 BD_manual_public_rbac_tables.md（public schema 8 张 RBAC/工作流表）
- 合并 biz.trigger_jobs 文档（10→12 字段，归档独立文档）
- docs/database/README.md 索引更新
