Remove application-level CORS and IP whitelisting as security is now handled at CloudFlare edge. CORS is not applicable for backend webhook service, and IP whitelisting is more effectively managed at infrastructure layer. Also translate Dockerfile comments to English and add registry URL to build script.

Implemented a production-ready TypeScript/Express.js service to receive
and log MailGun webhook events (delivered, failed, opened, clicked, etc.).
Key features:
- Webhook endpoint (POST /webhook) with comprehensive event logging
- Full TypeScript type definitions for all MailGun event types
- Prometheus metrics integration for monitoring
- Health check endpoint (GET /ping)
- Comprehensive Jest test suite with 87.76% coverage
- Docker containerization with build scripts
Removed template/example code:
- All SQL/MSSQL dependencies and related code
- Example auth router and middleware
- PRTG metrics support (simplified to Prometheus only)
- Unused middleware (CORS, IP whitelist, request parsing/validation)
- Template documentation (kept only MailGun webhook API spec)
The service is clean, minimal, and focused solely on receiving and
logging MailGun webhook events to the console.
