Updates for WebUI:

· [Important] Fixed the destruction issue with PriReader (caused by incorrect pointer types leading to unexecuted object destruction tasks).
· [Important] Added a program execution selection interface for packages containing multiple applications (still using WebUI).
 Issue: Since the selection window is set to close when losing focus, checking the "Launch when ready" option after successful installation causes the pop-up window to disappear when a Toast notification appears (due to focus loss). Currently, the selection window can only be displayed by clicking a button.
· [Optimization] Reduced the creation of PriReader objects to lower memory and storage consumption.
