fix: Refactor HTTPRoutePolicy status updates and test logic

Consolidate HTTPRoutePolicy status update functions by adding context.Context parameter and improving ancestor reference handling. Refactor e2e tests to use new helper functions for verifying HTTPRoutePolicy conditions, enhancing test reliability and readability while maintaining existing functionality.
