Add tests for configuration parser dangling reference fixes
Added comprehensive test coverage for the configuration parser dangling reference fixes that prevent GCC 15 warnings. These tests validate the new error handling paths introduced when fixing the unsafe pattern: const auto& obj = json.As<Type>().value().get(); // UNSAFE To the safe pattern: auto obj_result = json.As<Type>(); if (!obj_result.has_value()) { /* error handling */ } const auto& obj = obj_result.value().get(); // SAFE Test coverage includes: - ParseInstanceSpecifier() error handling for invalid JSON - ParseServiceTypeName() validation with malformed inputs - ParseVersion() handling of invalid version objects - ParseServiceInstanceDeployments() deployment validation - ParseAsilLevel() graceful handling of invalid types - ParseShmSizeCalcMode() error reporting for invalid modes - ParseAllowedUser() validation of user configurations - ParsePermissionChecks() default value handling Tests exercise the error handling through the public Parse() function with various malformed JSON configurations that trigger the specific error paths added in the dangling reference fixes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
