- Add ability to configure a decoy site on port 443 while hiding the web panel
- Support both same-port and separate-port configurations
- Add commands to manage decoy sites: 'decoy' to add/configure and 'stopdecoy' to remove
- Ensure clean reversion of Caddy configuration when stopping decoy sites
- Make decoy path optional during panel startup
This enhancement improves obfuscation capabilities by serving legitimate-looking
content on standard HTTPS port while keeping the actual panel hidden behind a
secret path.
