Fix remaining 7 code review issues

1-3. Add null checks for type and weaponDef before accessing in perferedUnit
4. Fix Spring.GetUnitCommands parameter - use fixed 100 instead of variable stockpile
5. Add null check for unit position before using in distance calculation
6. Add null check for tabButton.button before calling SetVisibility
7. Initialize WG.missileTotalCount in widget:Initialize to fix badge when disabled

All fixes are defensive nil/validation checks to prevent crashes.
