feat: add aigc regenerate flow and improve task polling

Add reusable RegenerateConfirmPopup component. Implement full regeneration flow in AIGC detail page with balance checks, insufficient point prompt, task creation and progress page navigation. Refine progress page polling logic with lifecycle handling, duplicate request prevention and timer cleanup.
