chore: remove caddy-related and obsolete files

Removed:
- Caddyfile: Caddy reverse proxy config (replaced by nginx.conf)
- setup_https.sh: Caddy HTTPS setup script
- https_manager.py: Caddy HTTPS management utility
- HTTPS_STATUS.txt: Old HTTPS documentation
- docker-compose.http.yml: HTTP-only Caddy compose file
- player_auth_module.py: Old authentication module (unused)
- player_config_template.ini: Old player config template (unused)
- test connection.txr: Test file

Updated:
- init-data.sh: Removed references to deleted caddy/obsolete files
- .dockerignore: Removed obsolete ignore entries

This completes the Caddy → Nginx migration cleanup.
