Fix NullPointerException in cart badge update

[cursor]

Summary

Fixes ANDROID-HZ

This PR addresses a NullPointerException that occurs when updating the cart badge count in EmpowerPlantActivity.

Problem

The app crashes with a NPE when calling setText() on textCartItemCount at line 144. This happens due to a race condition:

1. textCartItemCount is only initialized in onCreateOptionsMenu() (line 96)
2. onResume() subscribes to Room's observeSelectedCount() which emits immediately
3. The Room observer can fire before onCreateOptionsMenu() is called
4. When this happens, textCartItemCount is still null, causing the NPE

Solution

Added a null check before calling setText() on textCartItemCount. This defensive programming approach ensures that if the view hasn't been initialized yet, we simply skip the update. The badge will be updated once the view is available and the observer emits again.

Changes

• Modified onResume() method in EmpowerPlantActivity.java
• Added null check: if (textCartItemCount != null) before setting the text
• Converted lambda to block format to accommodate the conditional logic

Testing

The fix prevents the NPE while maintaining the same functionality. When the cart badge view is available, it will be updated correctly with the item count.
