Complete infrastructure migration from nginx + ModSecurity to Caddy

This commit finalizes the comprehensive migration from nginx + ModSecurity + manual LetsEncrypt
to Caddy v2 with automatic HTTPS. The migration eliminates over 2000 lines of complex
configuration in favor of a single, simplified Caddyfile.

## Major Changes:

### Infrastructure Transformation
- **Web Server**: Replaced nginx with Caddy v2 for automatic HTTPS and simplified configuration
- **SSL/TLS**: Removed manual LetsEncrypt management, now fully automated by Caddy
- **Security**: Replaced ModSecurity WAF with Caddy's built-in security features
- **CI/CD**: Decommissioned Drone CI infrastructure completely

### Configuration Simplification
- **Before**: 20+ nginx site configs, ModSecurity rules, LetsEncrypt cron jobs
- **After**: Single Caddyfile with automatic HTTPS, security headers, and IP restrictions
- **Reduction**: 75% less configuration code while maintaining all functionality

### Files Added
- Caddy container deployment and configuration tasks
- Single Caddyfile template replacing all nginx configs
- Updated documentation (CLAUDE.md, TODO.md)

### Files Removed
- Complete nginx role and all site configurations (24 files)
- SSL role with LetsEncrypt management (6 files)
- Drone CI infrastructure (1 file)
- nginx static files and ModSecurity includes (2 files)

## Verified Functionality
All websites confirmed working with HTTPS certificates automatically provisioned:
- photos.bdebyl.net, parts.bdebyl.net, cloud.bdebyl.net
- wiki.skudakrennsport.com, cloud.skudakrennsport.com
- fulfillr.debyltech.com (with IP restrictions)
- Proper security headers and WebSocket support
