feat(knowledge): 知识能挂附件，新建时就能传

知识是备忘录，备忘录不能只有字：手册、日志、导出表格都得能挂上去。附件本来就落在 item 上（`ALLOWED_KINDS` 早含 knowledge），缺的是"新建时还没有条目 id"这一段。 - 懒建草稿：`KnowledgeComposer` 第一次传附件（或往正文贴图）时先 `POST /knowledge` 存一条草稿拿到 id，`draftingRef` 去重防止贴图与上传同时打出两条草稿；之后的保存走 `PATCH /knowledge/{id}`。没传过附件就取消，库里不留空条目。 - `RichTextEditor` 增 `ensureItemId`：没有 itemId 时先把草稿存下来再传图，于是"新建时不能贴图"这条限制也没了；工具栏上传按钮按是否有落点显隐。 - 新建面板加了附件区：有草稿 id 就是正常的 `AttachmentPanel`（上传/下载/删），没有就先给一个「添加附件」按钮，点一下建草稿。 - 安卓知识详情加附件区：列表（文件名 + 大小）、`OpenDocument` 上传任意文件、点「打开」用浏览器看签名直链。编辑器原本只能插图，现在手册/日志也能传。 - 文档：API.md 说明附件三类事项共用同一套接口，以及懒建草稿的先后顺序； ROADMAP 加 3.13。验证：后端 pytest 94 passed、ruff 全绿；Web `tsc --noEmit` 通过、`vite build` 通过； `knowledge-notebook.mjs` 15 项全绿（新增「新建面板里能上传附件」「详情抽屉里能看到刚传的附件」「附件挂在知识上，详情回读得到」）。安卓端仍是 JDK 25 + Gradle 8.7 不兼容，本次未编译验证。
fix(knowledge): PATCH 知识时带上 doc_type 直接 500

 附件对象的字段：`id / item_id / filename / content_type / size / sha256 / uploader_id / created_at / raw_url / can_delete`。
 `raw_url` 是**后端签发的短期直链**（默认 30 分钟），客户端直接用它渲染，不需要自己拼令牌。
+附件可挂在 `kind` 为 `task / ticket / knowledge` 的事项上（`ALLOWED_KINDS`），知识与任务、工单共用同一套接口；
 事项与知识的列表接口会附带 `attachment_count`，详情接口附带 `attachments` 全量。

+新建知识时条目还不存在，前端用「懒建草稿」：点上传（或往正文里贴图）时先 `POST /knowledge` 存一条草稿拿到 `item_id`，
+再上传到 `/items/{item_id}/attachments`，之后的保存一律走 `PATCH /knowledge/{item_id}`。没传过附件就取消的人，库里不会留下空条目。
