CUB-125: implement real-time SSE/WebSocket in React frontend

- Add useSSE hook with exponential back-off reconnect (1s → 30s)
- Add useRealtimeSync hook: maps SSE events to React Query invalidation
  (agent.status → agents; agent.task/agent.progress → tasks+agents; fleet.update → all)
- Add SSEContext/SSEProvider so connection status is available app-wide
- Mount SSEProvider in main.tsx inside QueryClientProvider (no polling)
- Show live/connecting/reconnecting/disconnected badge in sidebar + mobile header
- Update SettingsPage: replace polling interval UI with SSE status panel
- Disable React Query polling (staleTime 60s); all updates pushed via SSE

-# Frontend
+# React + TypeScript + Vite
 
-This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 21.2.8.
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
 
-## Development server
+Currently, two official plugins are available:
 
-To start a local development server, run:
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
 
-```bash
-ng serve
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
 ```
 
-Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
 
-## Code scaffolding
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
 
-Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
-
-```bash
-ng generate component component-name
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
 ```
-
-For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
-
-```bash
-ng generate --help
-```
-
-## Building
-
-To build the project run:
-
-```bash
-ng build
-```
-
-This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
-
-## Running unit tests
-
-To execute unit tests with the [Vitest](https://vitest.dev/) test runner, use the following command:
-
-```bash
-ng test
-```
-
-## Running end-to-end tests
-
-For end-to-end (e2e) testing, run:
-
-```bash
-ng e2e
-```
-
-Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
-
-## Additional Resources
-
-For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.
