fix: address multiple code review issues across platform components

- Fix maxUsers input validation to prevent negative values and handle NaN cases - Enhance error handling in fetchCompany with detailed logging and context - Implement actual cache invalidation logic with pattern-based clearing - Add comprehensive cache optimization with memory management - Remove unsafe type casting in performance history analytics - Improve form validation and authentication patterns - Update documentation to mask sensitive data in examples
