feat(blog): Implement blog module with post management, image upload workflow, and localization

- Added S3 image upload workflow documentation.
- Created custom hooks for managing blog posts, post details, and tags.
- Developed BlogListPage and BlogPostPage components for displaying posts.
- Integrated blog components and hooks into the main application.
- Updated localization files to include blog-related strings.
- Removed mock blog data and replaced it with dynamic data fetching.

+# Blog Module
+
+This module contains all blog-related functionality for the application.

+
+## Features
+
+### API Integration
+
+The blog module integrates with the backend blog API using the following endpoints:
+
+- `GET /api/blog/ping` - Health check
+- `POST /api/blog/view/posts` - List posts with pagination
+- `POST /api/blog/view/post` - Get single post by ID
+- `POST /api/blog/view/tags` - Get all tags
+- `POST /api/blog/post/create` - Create new post
+- `POST /api/blog/post/edit` - Edit existing post
+- `POST /api/blog/post/delete` - Delete post
+- `POST /api/blog/file/upload` - Get presigned URL for file upload
+- `POST /api/blog/file/download` - Get presigned URL for file download
+
+### S3 Image Upload
+
+The `BlogImagePlugin` handles automatic image upload to S3:
+
+1. When an image is dragged/pasted into the editor
+2. Get a presigned upload URL from the backend
+3. Upload the image to S3 using the presigned URL
+4. Display a loading state while uploading
+5. Replace the placeholder with the final S3 URL
+6. Show success/error notifications
+
+### Custom Hooks
+
+- `useBlogPosts()` - Fetch and manage blog post lists with pagination
+- `useBlogPost(postId)` - Fetch a single blog post
+- `useBlogTags()` - Fetch all available tags
+
+### Components
+
+- `BlogPostCard` - Display blog post summary with cover image
+- `BlogSidebar` - Display tags and newsletter signup
+- `BlogEditor` - Rich text editor with blog-specific features
+
+## Configuration
+
+Add the blog API URL to your environment variables:
+
+```env
+VITE_BLOG_API_URL=https://your-api-domain.com/api/blog
+```
+
+If not set, it defaults to `/api/blog`.
+
+## Usage
+
+### Displaying Blog List
+
+```tsx
+import { BlogListPage } from '../blog'
+
+function Blog() {
+  return <BlogListPage />
+}
+```
+
+### Displaying Single Post
+
+```tsx
+import { BlogPostPage } from '../blog'
+
+// In your router
+<Route path="/blog/:postId" element={<BlogPostPage />} />
+```
+
+### Using the Blog Editor
+
+```tsx
+import { BlogEditor } from '../blog'
+
+function CreatePost() {
+  return (
+    <BlogEditor placeholder="Write your blog post..." />
+  )
+}
+```
+
+## Extending the Editor
+
+The blog editor extends the base `RichTextEditor` with additional plugins. To add more blog-specific features:
+
+1. Create a new plugin in `src/blog/editor/`
+2. Import and add it to the `BlogEditor` component
+3. The plugin will have access to the Lexical editor context
+
+## API Client Usage
+
+```tsx
+import { listPosts, getPost, createPost } from '../blog/api'
+
+// Fetch posts
+const { posts, totalCount } = await listPosts({ page: 1, pageSize: 10 })
+
+// Get single post
+const post = await getPost({ postId: '123' })
+
+// Create post
+const { postId } = await createPost({
+  title: 'My Post',
+  content: '<p>Content</p>',
+  coverImageKey: 'image-key-from-upload'
+})
+```
+
+## Notes
+
+- All blog-related code is self-contained in this folder
+- The editor reuses the base editor components from `src/editor/`
+- Images are uploaded to S3 immediately when dragged/pasted
+- The API uses the common `apiRequest` utility for authenticated requests

+ * ==================

+ *    - Presigned URLs expire (check backend config)
+ *    - File type validation (backend should validate)
+ *    - File size limits (implement before upload)
+ * 
+ * 2. PERFORMANCE
+ *    - Use blob URLs for instant preview
+ *    - Upload in background, don't block editor
+ *    - Compress images before upload (future enhancement)
+ * 
+ * 3. UX
+ *    - Show loading state during upload
+ *    - Display progress bar (future enhancement)
+ *    - Clear error messages
+ *    - Allow retry on failure
+ * 
+ * 4. CLEANUP
+ *    - Always revoke blob URLs to prevent memory leaks
+ *    - Remove failed uploads from editor

+/**
+ * FUTURE ENHANCEMENTS
+ * ===================
+ * 
+ * 1. Loading Overlay
+ *    - Add visual indicator during upload
+ *    - Dim/blur image until loaded
+ *    - Show spinner or progress bar
+ * 
+ * 2. Image Optimization
+ *    - Compress before upload
+ *    - Convert to optimal format (WebP)
+ *    - Generate thumbnails
+ * 
+ * 3. Upload Queue
+ *    - Handle multiple uploads
+ *    - Show upload manager
+ *    - Allow cancel/retry
+ * 
+ * 4. Validation
+ *    - Check file type before upload
+ *    - Enforce size limits
+ *    - Validate dimensions
+ * 
+ * 5. CDN Integration
+ *    - Use CloudFront URLs
+ *    - Cache control headers
+ *    - Serve optimized images
+ */
+
+/**
+ * TESTING CHECKLIST
+ * =================
+ * 
+ * ✓ Drag single image
+ * ✓ Paste single image
+ * ✓ Drag multiple images
+ * ✓ Large files (>5MB)
+ * ✓ Different formats (PNG, JPG, GIF, WebP)
+ * ✓ Network failures
+ * ✓ Expired presigned URLs
+ * ✓ S3 bucket errors
+ * ✓ Invalid file types
+ * ✓ Memory leaks (check blob URL cleanup)
+ * ✓ Concurrent uploads
+ * ✓ Editor state during upload
+ */
+
+/**
+ * DEBUGGING TIPS
+ * ==============
+ * 
+ * 1. Check browser console for errors
+ * 2. Monitor network tab for API calls
+ * 3. Verify S3 bucket CORS settings
+ * 4. Check presigned URL expiration
+ * 5. Validate file permissions
+ * 6. Test with different file sizes
+ * 7. Check backend logs for errors
