Replace the blocking spin_processing_tasks_with_source_until calls in apply_the_history_step_after_unload_check() with an event-driven ApplyHistoryStepState GC cell that tracks 5 phases, following the same pattern used by CheckUnloadingCanceledState. Key changes: - Introduce ApplyHistoryStepState with phases: WaitingForDocumentPopulation, ProcessingContinuations, WaitingForChangeJobCompletion, WaitingForNonChangingJobs and Completed - Add on_complete callbacks to apply_the_push_or_replace_history_step, finalize_a_same_document_navigation, finalize_a_cross_document_navigation, and update_for_navigable_creation_or_destruction - Remove spin_until from Document::open() - Use null-document tasks for non-changing navigable updates and document unload/destroy to avoid stuck tasks when documents become non-fully-active - Defer completely_finish_loading when document has no navigable yet, and re-trigger post-load steps in activate_history_entry for documents that completed loading before activation Co-Authored-By: Shannon Booth <shannon@serenityos.org>
