feat: Enhanced WhatsApp template support with security optimizations
- Add comprehensive WhatsApp template parameter support for header/footer/buttons - Implement coupon code template support with 15-character validation - Support all WhatsApp template types (text, media, interactive) - Add advanced parameter types (currency, date/time, location) - Remove restrictions on DOCUMENT, IMAGE, VIDEO template formats Security improvements: - Fix XSS vulnerability by replacing v-html with v-dompurify-html - Add input sanitization and parameter validation - Implement URL validation with scheme and length checks - Add protection against DoS attacks with length limits Performance optimizations: - Replace recursive template fetching with iterative pagination - Add safety limits to prevent infinite loops and stack overflow - Optimize template processing for better memory usage Frontend enhancements: - Enhanced template picker with header/footer/button display - Component-based parameter input organized by type - Real-time validation for coupon codes and parameters - Improved template preview with sanitized HTML rendering - Fix Vue linting issues with proper computed properties Maintains full backward compatibility with existing template configurations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
