Subject: [PATCH] CRITICAL FIX: Add /dev/tty redirection and error handling to
 all read commands

- Fix run_module() read commands (lines 59, 80) with /dev/tty and error handler
- Fix all submenu handler read commands with /dev/tty redirection:
  * handle_threat_analysis_menu (line 199)
  * handle_live_monitoring_menu (line 233)
  * handle_log_viewers_menu (line 265)
  * handle_security_actions_menu (line 296)
  * handle_security_menu (line 330)
  * handle_website_menu (line 378)
  * handle_performance_menu (line 431)
  * handle_backup_menu (line 537)
  * handle_acronis_menu (line 552)
  * handle_email_menu (line 606)
- Fix startup_detection() call with error handler (line 699)

Impact: Prevents tmux crashes on non-interactive terminals by gracefully handling read failures. Closes terminal crash issue on AlmaLinux 8.
