feat: add progress bar UI and styled placeholder images
- Add overall progress bar with percentage during page generation - Add per-page progress indicators with checkmarks for completed pages - Show current page title/type while generating - Create styled placeholder images with actual page content when AI image generation is geo-blocked - Style placeholders match selected zine style (punk, minimal, etc.) - Add cache-busting timestamps to force image reload - Update worker to return helpful error for geo-blocking 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
