- Replace old cookie logic with `Set_Cookie()` for enhanced security (SameSite, Secure, HttpOnly).
- Add dynamic AIX/Linux filtering on `/X/Inventory.php` with checkbox-driven UI and adjusted SQL queries.
- Expand `/X/Inventory.php` table with additional columns (`BES`, `FI`) and enhance data validation/styling.
- Add `decypher()` function in `Z_data_linux.php` to support OpenSSL-based file decryption with error handling.
- Deleted `cluster-detail2.php`, `constants.inc copy.php`, `D.php`, and `Dashboard2.php`. These files were no longer in use and contributed to unnecessary clutter in the codebase.
- Cleaned up references to removed files.
