Enhance configuration and documentation for CIDR and IP handling. Updated config.example.yaml to include additional whitelisted IPs and new server entries. Improved GATEWAY_RUN.md to clarify CIDR and single IP usage. Implemented parseCIDROrIP function in config.go for better validation of IP formats in whitelist and trusted proxies.
