chore(plugins): Convert All Plugins Using entity-registry to Spring Configuration

[alexsku]

This PR completes the migration of all remaining plugins from YAML configuration in entity-registry.yml to Spring beans, unifying the plugin management system under Spring's dependency injection framework. 8 plugins have been successfully migrated across aspectPayloadValidators, mutationHooks, and mcpSideEffects categories, including CreateIfNotExistsValidator, ConditionalWriteValidator, FieldPathMutator, OwnershipOwnerTypes, StructuredPropertiesSoftDelete, PropertyDefinitionValidator, StructuredPropertiesValidator, and PropertyDefinitionDeleteSideEffect. All plugins now follow a consistent Spring bean pattern in SpringStandardPluginConfiguration.java with proper AspectPluginConfig setup and corresponding test coverage, providing better type safety, compile-time validation, and unified configuration management while maintaining full backward compatibility and functionality.
