ESP working: NPC detection + authoritative server-side health

- entitylist slot 6 (GetHighestEntityIndex); class name via
  GetClientNetworkable -> GetClientClass (replaces the unsafe slot-2 call)
- HL2 SP NPCs: class CAI_BaseNPC + m_lifeState, since NPC m_iHealth is not
  networked; model names from VModelInfoClient006 for labels/friend-foe
- real HP/HP-max from the listen-server entity (IVEngineServer021 ->
  PEntityOfEntIndex -> edict->m_pUnk -> GetBaseEntity) using offsets scanned
  from server.so's datamap; validated against the client model index
- world_to_screen via IVDebugOverlay003::ScreenPosition (fixes box drift)
- maxs sanity clamp, NPC-only debug logging, neutral colour for wildlife
- build.sh: restore -o libhl2hake.so and add server.cpp
