feat: Add database and Sentry integration for Open Graph Generator

This commit introduces comprehensive database and error tracking features:

- Implement SQLite database for tracking image generation history
- Add Sentry integration for error monitoring and performance tracking
- Create database.go with robust generation record management
- Add sentry.go with comprehensive error reporting middleware
- Update server and service components to use new database and error tracking
- Enhance environment configuration with Sentry and database settings
- Implement automated cleanup scheduler for generated files
- Add admin authentication middleware for sensitive endpoints

The changes provide improved tracking, error visibility, and system reliability for the Open Graph image generation service.
