Add mission customization, HQ support and aggression-driven AI

Integrate faction and random settings menus, generated objectives, scouts, convoys, air support, mortar stations and body-intel recovery. Add identified-body aggression, finite hunter UAZ deployment, dedicated objective defence and maximum AI skill with separate reduced aim accuracy. Include policy tests, native probes, evidence and documentation.
