  - Added User Management Interface (Create, Delete, Enable/Disable)
  - Added Device Mapping view in iSCSI tab (lsscsi output)
- Backend:
  - Implemented secure session management (auth.php)
  - Added power management APIs (restart/shutdown appliance)
  - Added device mapping API
- CLI:
  - Created global 'vtl' management tool
  - Added scripts for reliable startup (vtllibrary fix)
- Installer:
  - Updated install.sh with new dependencies (tgt, sudoers, permissions)
  - Included all new components in build-installer.sh
- Docs:
  - Consolidated documentation into docs/ folder
