feat: import CarLog v2.8 code + dev plan

把 CarLog v2.8 全套源码 + 配置导入到 i 仓库作为 baseline:
- server/src/ (13 个路由 + middleware + services + config)
- server/migrations/ (0001~0018 共 18 个迁移 + mysql)
- server/test/ (12 文件 101 测试)
- client/src/ (20 个 view + components + stores + api + composables)
- client/public/ + client/scripts/
- 全部配置文件 (.editorconfig, .eslintrc.json, .prettierrc.json, vitest.config.js, lighthouserc.json, .pa11yci.json, package.json, carlog-init.sql)
- .husky/pre-commit (git hooks)
- docs/install/ (宝塔部署文档)

不含:
- node_modules/ (本地 npm install)
- .env (敏感, 走 .env.example)
- *.zip / *.log / *.sqlite / .DS_Store

新增文档 docs/DEV-PLAN.md:
- Phase 1: 平台基座 (019 migration + 3 个 platform 路由 + 3 个 view)
- Phase 2: CarLog 子系统化 (后端 routes/ → subsystems/carlog/ + 前端 views/ → views/subsystems/carlog/ + 元数据驱动菜单)
- Phase 3: 验证 (测试 + E2E + DB 完整性)
- 交付清单 + commit 模板 + 给 Mavis review 的材料

后续 Trae 实施, 提交后我 code review + 跑测试。
