Fix hostile target selection when faction flags are wrong

- make tab-target accept units that are either faction-hostile or actively aggressive toward the player\n- fix cases where enemies remain un-tab-targetable after combat starts due to stale/friendly faction state\n- prefer hostile UNIT picks over nearby GAMEOBJECT picks for both left-click target and right-click interact flows\n- keep existing dead-unit filtering and interaction behavior intact while improving combat target acquisition
