chore(格式): Prettier 统一到全仓，后端和契约一次性格式化

原来只有 `apps/web` 在 Prettier 下（配置在 `apps/web/.prettierrc.toml`、脚本在
web 的 package.json），后端和契约从来没格式化过 —— 手写在 100 列上下，`db/schema.ts`
还是 drizzle-kit pull 留下的 tab 缩进。两套口径分叉久了，跨端改一处就得记着「这边
什么风格」。

- 配置搬到根目录 `.prettierrc.toml`，内容不变（`semi=false`，其余全默认，
  printWidth 80 —— 和前端已有的格式一致，不另立一套宽度）；
- 脚本统一成根目录 `bun run fmt`，覆盖 `apps/*/src`、`apps/web/tests` 和两个构建
  配置；web 自己那份 `fmt` 和重复的 prettier 依赖删掉；
- `.prettierignore` 挡掉两类不该碰的：drizzle-kit 生成的 `src/db/meta/` 结构快照
  （它是 db:generate 的比对输入，只该由 drizzle-kit 写）、unplugin 每次 dev 都会
  重写的 `auto-imports.d.ts` / `components.d.ts`；
- 全量跑了一遍。纯格式，无行为改动：api typecheck / check:routes / check:ast、
  前端 type-check 全过，起 api 打了接口确认正常。前端这 39 个文件的小改动是
  prettier 版本漂移（类型断言的换行口径变了），不是新配置带来的。
