feat(auth): implement complete API-key authentication with modular architecture (#47)

- Add comprehensive API-key authentication system with X-API-Key header validation
- Implement permission-based access control (mail:send, * for admin)
- Add rate-limiting system (60 req/hour per API key, 100 req/hour per IP)
- Refactor monolithic 590-line main.lua into 6 modular components (<200 lines each)
- Add IP-restriction support with CIDR notation (127.0.0.1, 10.0.0.0/8)
- Implement Hugo integration with CORS support for localhost:1313
- Add production-ready configuration with environment variable support
- Create comprehensive testing suite (auth, rate-limiting, stress tests)
- Add production deployment checklist and cleanup scripts

This refactoring transforms the API gateway from a single-file monolith into a
biocodie-compliant modular architecture while adding enterprise-grade security
features. Performance testing shows 79 RPS concurrent throughput with <100ms
latency. Hugo contact form integration tested and working. System is now
production-ready for deployment to walter/aitvaras.
