feat: WordPress Media Modal Integration! 🎉

## ✅ Improvements 4-5 Complete - Respecting WordPress!

### 4. WordPress Media Modal for TipTap Images
**Before:**
- Prompt dialog for image URL
- Manual URL entry
- No media library access

**After:**
- Native WordPress Media Modal
- Browse existing uploads
- Upload new images
- Full media library features
- Alt text, dimensions included

**Implementation:**
- `wp-media.ts` helper library
- `openWPMediaImage()` function
- Integrates with TipTap Image extension
- Sets src, alt, title automatically

### 5. WordPress Media Modal for Store Logos/Favicon
**Before:**
- Only drag-and-drop or file picker
- No access to existing media

**After:**
- "Choose from Media Library" button
- Filtered by media type:
  - Logo: PNG, JPEG, SVG, WebP
  - Favicon: PNG, ICO
- Browse and reuse existing assets
- Professional WordPress experience

**Implementation:**
- Updated `ImageUpload` component
- Added `mediaType` prop
- Three specialized functions:
  - `openWPMediaLogo()`
  - `openWPMediaFavicon()`
  - `openWPMediaImage()`

## 📦 New Files:

**lib/wp-media.ts:**
```typescript
- openWPMedia() - Core function
- openWPMediaImage() - For general images
- openWPMediaLogo() - For logos (filtered)
- openWPMediaFavicon() - For favicons (filtered)
- WPMediaFile interface
- Full TypeScript support
```

## 🎨 User Experience:

**Email Builder:**
- Click image icon in RichTextEditor
- WordPress Media Modal opens
- Select from library or upload
- Image inserted with proper attributes

**Store Settings:**
- Drag-and-drop still works
- OR click "Choose from Media Library"
- Filtered by appropriate file types
- Reuse existing brand assets

## 🙏 Respect to WordPress:

**Why This Matters:**
1. **Familiar Interface** - Users know WordPress Media
2. **Existing Assets** - Access uploaded media
3. **Better UX** - No manual URL entry
4. **Professional** - Native WordPress integration
5. **Consistent** - Same as Posts/Pages

**WordPress Integration:**
- Uses `window.wp.media` API
- Respects user permissions
- Works with media library
- Proper nonce handling
- Full compatibility

## 📋 All 5 Improvements Complete:

✅ 1. Heading Selector (H1-H4, Paragraph)
✅ 2. Styled Buttons in Cards (matching standalone)
✅ 3. Variable Pills for Button Links
✅ 4. WordPress Media for TipTap Images
✅ 5. WordPress Media for Store Logos/Favicon
