fix: Replace Prawn with Grover for PDF ticket generation
- Replace Prawn PDF generation with Grover (Chrome headless) for better compatibility - Add HTML-based ticket template with embedded CSS styling - Implement robust Grover loading with fallback to HTML download - Add QR code generation methods to Ticket model - Remove legacy TicketPdfGenerator service and tests - Update PDF generation in TicketsController with proper error handling The new implementation provides: - Better HTML/CSS rendering for ticket layouts - More reliable PDF generation using Chrome engine - Fallback mechanism for better user experience - Cleaner separation of template rendering and PDF conversion 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
