Fix remaining FTL macro NPE errors in form-list rendering.

- Safe navigation of formNode and fieldNode attributes using ?parent
- Fallback to empty string for null field values in display/text macros
- Use getActiveScreenDef() for screen name resolution in formListWidget
- Prevents NullPointerException in EditPrices and other list screens.
