refactor: Update NewWrapper_V2 padding defaults

- Change default paddingTop to 8
- Change default paddingHorizontal to 0 (safe for existing layouts)
- Add explicit contentPaddingHorizontal={16} to Job screens
- Update interface documentation

This makes NewWrapper_V2 safer for mass migration while keeping
Job screens looking good with proper spacing.
