fix: Address PR review comments

- Remove redundant useMemo wrapper in usePatternValidation
  Inline the calculation logic directly in useMemo instead of
  useCallback + useMemo pattern for better clarity and efficiency

- Remove unnecessary 'Early return' comment in usePatternRotationUpload
  The return statement is self-explanatory
