feat: action log registration, Moko theme defaults, security defaults

- Register plg_system_mokowaas in #__action_logs_extensions on install
  so emergency access events appear as filterable in Action Logs UI
- Unregister on uninstall
- Set Moko brand colors as defaults: navy #1a2744, dark #0f1b2d,
  accent green #2ecc71
- Force HTTPS default: Yes (was No)
- Admin session timeout default: 60 minutes (was 0/disabled)
