feat: add social image generator with GD-based OG image compositing (#157) 1aa58e1d8d 
Replace basic single-size OG image generation with full-featured
multi-platform social image compositing:

- Platform-specific canvas sizes: Facebook 1200x630, Twitter 1200x675,
  Instagram 1080x1080, Stories 1080x1920
- Vertical linear gradient fallback when no source image available
- Semi-transparent overlay with configurable color and opacity (0-100%)
- Logo placement in top-right corner, auto-scaled to 15% of canvas width
- TTF text rendering with word wrap and text shadow for readability
- GD bitmap font fallback when no TTF fonts are available
- Configurable text position: top, center, or bottom
- Output to images/mokosuitecross/{articleId}_{platform}.jpg
- Cache clearing per article via clearCache() method
- ImageController AJAX endpoint with platform parameter validation
- Full config fieldset: enabled toggle, overlay color/opacity,
  text color/position, gradient start/end, logo upload
