Allow authenticated (non-admin) users to fetch API key usage by replacing @admin_required with @auth_required in api_analytics.py and importing auth_required. Add optional user support to privileged_cmd and run_privileged in app/utils/system.py so callers can run commands as a specific user (sudo -u). Update wordpress_service to use the new user keyword when invoking privileged commands. Fix tests/conftest.py to put the backend root (parent directory) on sys.path so tests import correctly.
Introduce safer system interactions and improved logging fallbacks across services. Replace direct sudo/subprocess calls with run_privileged/privileged_cmd, add command availability checks (is_command_available) and Linux guards for user management. Enhance LogService with fallback readers (python file I/O, grep fallback, syslog and Windows Event Log support) and standardize responses via sourced_result. Update frontend Terminal to display log source and adjust UI when journalctl is unavailable. Misc: delegate ProcessService log retrieval to LogService, add PackageManager usage in PHP/SSL installs, and add warning logging in DeploymentService when diff generation fails.
Backend: Replace direct sudo/subprocess.run calls with run_privileged and privileged_cmd, add _needs_sudo/privileged_cmd logic and is_command_available checks, and return clearer errors for missing binaries (journalctl/grep/tail/truncate/logrotate/systemctl/service). Add FileNotFoundError handling and use privileged_cmd for Popen.
Frontend: UI and style refinements across Downloads, Security and Terminal pages — simplified Linux icon, added release date and banner actions, redesigned scanner UI into interactive scan cards with custom path and toolbar, handle unavailable journalctl with an empty state, update SVG icons. Styles (.less): switch mono font to JetBrains Mono, adjust spacing/gaps, sidebar text truncation, revamp downloads and security card styles, and improve terminal log fonts, wrapping and processes table layout.
Refactor services to use centralized system helpers (ServiceControl, PackageManager, run_privileged, is_command_available) instead of ad-hoc subprocess/os calls. Updated deployment, firewall, ftp, nginx, php, python, security, and ssl services to call the new utilities and added error/timeout handling improvements and package manager abstraction. Added backend/app/utils/system.py implementing the helpers and backend/tests/test_utils_system.py with unit tests. This centralizes privileged command execution and service/package management, simplifying tests and platform differences.
