Add strict delegation target validation with secure defaults and explicit allowlist support. Block local/private/link-local/metadata destinations, reject redirects, and extend tests/docs including example config updates.

This pull request introduces a comprehensive security layer for outbound operation delegation in the Submodel Repository feature. The main changes include validating all outbound delegation URIs, blocking potentially unsafe targets by default, supporting allowlists for approved exceptions, and improving error handling and configuration. These changes significantly enhance the safety and configurability of operation delegation.
Security enhancements for operation delegation
OperationDelegationTargetValidatorclass to validate outbound delegation targets, blocking loopback, private, link-local, and metadata addresses, and only allowinghttp/httpsschemes by default. Explicit allowlists for hosts, CIDRs, and ports are supported.OperationDelegationSecurityPropertiesto expose all relevant security configuration options, including toggles for each blocking rule and allowlist settings.OperationDelegationSubmodelRepositoryConfiguration) to wire in the validator and properties, and to enforce validation on every outbound HTTP request.Runtime and error handling improvements
HTTPOperationDelegationto reject HTTP redirects, improve error messages, and ensure all exceptions are wrapped asOperationDelegationException.Readme.md) to describe the new security defaults, configuration options, and allowlist usage for hybrid deployments.
