Subject: [PATCH] feat: enhance plugin page internationalization (#7998)

* feat: enhance plugin page internationalization

- Updated PluginRoute to read initial context from JWT and set it in the bridge SDK.
- Added methods to retrieve locale and plugin metadata for better i18n support.
- Enhanced pluginI18n utility to resolve page-specific translations and added new functions for page titles and descriptions.
- Modified PluginPagePage and PluginDetailPage to utilize new i18n features for dynamic content rendering.
- Improved documentation for plugin page i18n structure and usage.
- Added tests to verify the correct integration of i18n in plugin pages and context handling.

* fix test

+

 ```
 
 `endpoint` must be a plugin-local path. It must not be empty, contain `\`, contain a URL scheme, contain query strings or fragments, or contain `.` / `..` path segments.
 
+## Page Internationalization
+
+Plugin Pages reuse plugin i18n resource files. Add `pages.<page_name>` to `.astrbot-plugin/i18n/<locale>.json`:
+
+```json
+{
+  "pages": {
+    "bridge-demo": {
+      "title": "Bridge Demo",
+      "description": "Shows how a plugin page reads the WebUI locale and translations.",
+      "heading": "Plugin Page",
+      "refresh": "Render again"
+    }
+  }
+}
+```
+
+`title` is used by the WebUI shell title and the Page component name on the plugin detail page. `description` is used by the Page component description on the plugin detail page.
+
+Inside the Page, render text with `t()` and react to language changes with `onContext()`:
+
+```js
+const bridge = window.AstrBotPluginPage;
+
+function render() {
+  document.title = bridge.t("pages.bridge-demo.title", "Bridge Demo");
+  document.getElementById("heading").textContent = bridge.t(

+  document.getElementById("locale").textContent = bridge.getLocale();
+}
+
+await bridge.ready();
+render();
+bridge.onContext(render);
+```
+
+After the WebUI locale changes, the Dashboard sends the new `locale` and plugin i18n resources to the iframe through the bridge. If the Page listens with `onContext()`, it usually does not need a refresh.
+
+If an inline script needs to access `window.AstrBotPluginPage` synchronously, move the code to an external module file or explicitly include the bridge SDK before your script:

+
+## Appendix: Bridge API Details
+
+Start page scripts by keeping a bridge reference:
+
+```js
+const bridge = window.AstrBotPluginPage;
+```
+
+### `ready()`
+
+Waits for the parent page to send the initial context and returns `Promise<context>`. Page initialization should wait for this before reading context-dependent values.
+
+```js
+const context = await bridge.ready();
+console.log(context.pluginName, context.pageName, context.locale);
+```
+
+The context usually contains:
+
+```json
+{
+  "pluginName": "astrbot_plugin_page_demo",
+  "displayName": "Plugin Page Demo",
+  "pageName": "bridge-demo",
+  "pageTitle": "Bridge Demo",
+  "locale": "en-US",
+  "i18n": {}
+}
+```
+
+### `getContext()`
+
+Synchronously reads the latest context. Use it after `ready()` or inside an `onContext()` callback.
+
+```js
+function renderHeader() {
+  const context = bridge.getContext();
+  document.getElementById("title").textContent = context.pageTitle;
+}
+```
+
+### `getLocale()`
+
+Synchronously reads the current WebUI locale. It returns `zh-CN` when no context exists yet.
+
+```js
+document.documentElement.lang = bridge.getLocale();
+```
+
+### `getI18n()`
+
+Synchronously reads the full plugin i18n resource object. Prefer `t()` for normal rendering; use this for custom traversal or debugging.
+
+```js
+console.log(Object.keys(bridge.getI18n()));
+```
+
+### `t(key, fallback)`
+
+Reads text from plugin i18n by dot-separated key. If the current locale is missing, the bridge tries fallbacks; if still missing, it returns `fallback`.
+
+```js
+saveButton.textContent = bridge.t("pages.settings.save", "Save");
+```
+
+### `onContext(handler)`
+
+Listens for context changes and returns an unsubscribe function. The callback runs when the WebUI locale changes, so pages that need live language switching should rerender here.
+
+```js
+function render() {
+  document.title = bridge.t("pages.settings.title", "Settings");
+}
+
+await bridge.ready();
+render();
+
+const off = bridge.onContext(render);
+
+window.addEventListener("beforeunload", () => {
+  off();
+});
+```
+
+### `apiGet(endpoint, params)`
+
+Sends a GET request to the plugin backend and returns `Promise<data>`. `endpoint` is a plugin-local relative path; the Dashboard forwards it to `/api/plug/<plugin_name>/<endpoint>`.
+
+```js
+const stats = await bridge.apiGet("stats", { limit: 20 });
+```
+
+Backend registration example:
+
+```python
+context.register_web_api(
+    f"/{PLUGIN_NAME}/stats",
+    self.get_stats,
+    ["GET"],
+    "Get stats",
+)
+```
+
+### `apiPost(endpoint, body)`
+
+Sends a POST request to the plugin backend. `body` is sent as JSON and the method returns `Promise<data>`.
+
+```js
+await bridge.apiPost("settings/save", {
+  enabled: true,
+  threshold: 0.8,
+});
+```
+
+### `upload(endpoint, file)`
+
+Uploads one file as `multipart/form-data` with the field name `file`, returning `Promise<data>`.
+
+```js
+const input = document.querySelector("input[type=file]");
+const file = input.files[0];
+const result = await bridge.upload("files/import", file);
+```
+
+### `download(endpoint, params, filename)`
+
+Requests a plugin backend file endpoint and triggers a browser download. `params` are sent as query parameters. `filename` is optional; when omitted, the bridge tries to use the response filename header.
+
+```js
+await bridge.download("files/export", { format: "json" }, "export.json");
+```
+
+### `subscribeSSE(endpoint, handlers, params)`
+
+Subscribes to plugin backend SSE and returns `Promise<subscriptionId>`. `handlers` may include `onOpen`, `onMessage`, and `onError`.
+
+```js
+const subscriptionId = await bridge.subscribeSSE(
+  "events",
+  {
+    onOpen() {
+      console.log("SSE opened");
+    },
+    onMessage(event) {
+      console.log(event.raw, event.parsed, event.lastEventId);
+    },
+    onError() {
+      console.warn("SSE error");
+    },
+  },
+  { topic: "logs" },
+);
+```
+
+`event.parsed` is automatically parsed when the message is a JSON string; otherwise it equals the raw string.
+
+### `unsubscribeSSE(subscriptionId)`
+
+Cancels an SSE subscription.
+
+```js
+await bridge.unsubscribeSSE(subscriptionId);
+```
+
+Clean up subscriptions when the page unloads:
+
+```js
+window.addEventListener("beforeunload", () => {
+  bridge.unsubscribeSSE(subscriptionId);
+});
+```
+
+### endpoint Rules
+
+The `endpoint` used by `apiGet`, `apiPost`, `upload`, `download`, and `subscribeSSE` must be a plugin-local relative path:
+
+- Allowed: `"stats"`, `"settings/save"`, `"files/export"`
+- Not allowed: empty string, `"/stats"`, `"../stats"`, `"https://example.com"`, `"stats?x=1"`, `"stats#top"`
+
+Pass query parameters through `params`; do not append them to `endpoint`.

+
+```js
+function renderHeader() {
+  const context = bridge.getContext();
+  document.getElementById("title").textContent = context.pageTitle;
+}
+```
+
+### `getLocale()`
+
+同步读取当前 WebUI 语言。没有上下文时默认返回 `zh-CN`。
+
+```js
+document.documentElement.lang = bridge.getLocale();
+```
+
+### `getI18n()`
+
+同步读取当前插件的完整 i18n 资源对象。一般优先用 `t()`，只有需要自定义遍历或调试时才直接读取。
+
+```js
+console.log(Object.keys(bridge.getI18n()));
+```
+
+### `t(key, fallback)`
+
+按点分隔 key 从插件 i18n 中取文案。当前语言缺失时会尝试回退，仍缺失则返回 `fallback`。
+
+```js
+saveButton.textContent = bridge.t("pages.settings.save", "Save");
+```
+
+### `onContext(handler)`
+
+监听上下文变化，返回取消监听函数。WebUI 切换语言时会触发该回调，所以需要响应语言切换的页面应在这里重新渲染。
+
+```js
+function render() {
+  document.title = bridge.t("pages.settings.title", "Settings");
+}
+
+await bridge.ready();
+render();
+
+const off = bridge.onContext(render);
+
+window.addEventListener("beforeunload", () => {
+  off();
+});
+```
+
+### `apiGet(endpoint, params)`
+
+向插件后端发送 GET 请求，返回 `Promise<data>`。`endpoint` 是插件内相对路径，Dashboard 会转发到 `/api/plug/<plugin_name>/<endpoint>`。
+
+```js
+const stats = await bridge.apiGet("stats", { limit: 20 });
+```
+
+后端注册示例：
+
+```python
+context.register_web_api(
+    f"/{PLUGIN_NAME}/stats",
+    self.get_stats,
+    ["GET"],
+    "Get stats",
+)
+```
+
+### `apiPost(endpoint, body)`
+
+向插件后端发送 POST 请求，`body` 会作为 JSON 请求体发送，返回 `Promise<data>`。
+
+```js
+await bridge.apiPost("settings/save", {
+  enabled: true,
+  threshold: 0.8,
+});
+```
+
+### `upload(endpoint, file)`
+
+以 `multipart/form-data` 上传单个文件，字段名为 `file`，返回 `Promise<data>`。
+
+```js
+const input = document.querySelector("input[type=file]");
+const file = input.files[0];
+const result = await bridge.upload("files/import", file);
+```
+
+### `download(endpoint, params, filename)`
+
+请求插件后端文件接口并触发浏览器下载。`params` 会作为 query string，`filename` 可选；不传时会尝试使用响应头里的文件名。
+
+```js
+await bridge.download("files/export", { format: "json" }, "export.json");
+```
+
+### `subscribeSSE(endpoint, handlers, params)`
+
+订阅插件后端 SSE，返回 `Promise<subscriptionId>`。`handlers` 可包含 `onOpen`、`onMessage`、`onError`。
+
+```js
+const subscriptionId = await bridge.subscribeSSE(
+  "events",
+  {
+    onOpen() {
+      console.log("SSE opened");
+    },
+    onMessage(event) {
+      console.log(event.raw, event.parsed, event.lastEventId);
+    },
+    onError() {
+      console.warn("SSE error");
+    },
+  },
+  { topic: "logs" },
+);
+```
+
+`event.parsed` 会在消息内容是 JSON 字符串时自动解析，否则等于原始字符串。
+
+### `unsubscribeSSE(subscriptionId)`
+
+取消 SSE 订阅。
+
+```js
+await bridge.unsubscribeSSE(subscriptionId);
+```
+
+页面卸载时建议清理订阅：
+
+```js
+window.addEventListener("beforeunload", () => {
+  bridge.unsubscribeSSE(subscriptionId);
+});
+```
+
+### endpoint 规则
+
+`apiGet`、`apiPost`、`upload`、`download`、`subscribeSSE` 的 `endpoint` 必须是插件内相对路径：
+
+- 允许：`"stats"`、`"settings/save"`、`"files/export"`
+- 不允许：空字符串、`"/stats"`、`"../stats"`、`"https://example.com"`、`"stats?x=1"`、`"stats#top"`
+
+query 参数请通过 `params` 传递，不要拼进 `endpoint`。
