Fix NullPointerException in EmpowerPlantActivity cart count observer

[cursor]

Summary

Fixes a NullPointerException that occurs when the cart count observer fires before the options menu is inflated in EmpowerPlantActivity.

Problem

The cart item count LiveData observer in onResume() was calling setText() on textCartItemCount without checking if it was null. Since onResume() runs before onCreateOptionsMenu() in the Activity lifecycle, textCartItemCount would be null when the observer first fires, causing the app to crash on startup.

Solution

Added a null check before calling setText() on textCartItemCount in the cart count observer. This prevents the crash while still allowing the cart badge to update once the menu is inflated.

Testing

• Launch the Android app and open EmpowerPlantActivity
• Ensure the cart has items
• Activity no longer crashes on startup
• Cart badge updates correctly once the menu is created
