Optimize OrganizeTroopsCommandSelector for better responsiveness

Performance improvements:
- Remove redundant Update() calls in PlusClickedImpl methods - the caller
  (UpdateTable or MaxClickedImpl) calls Update() when needed
- Remove unused Update() call in MinusClicked (result was never used)
- Cache extraTroops counts by type to avoid repeated LINQ queries on each
  battalion row
- Fix somethingChanged check to inspect fields directly instead of calling
  expensive Update() method inside Exists()
- Remove duplicate maxAllButton.SetActive(false) call

These changes reduce the number of object allocations and iterations
performed on each button click, improving UI responsiveness.
