AI: use server relationships to classify NPC friendliness

- Read the server NPC's m_Relationship CUtlVector (entity row for the local
  player first, then the CLASS_PLAYER row): D_LI friendly, D_NU neutral,
  D_HT/D_FR hostile.
- Use it for ESP colours and aimbot/silent-aim/melee target filtering, with
  the existing model heuristic as a fallback.
- Treat bugbait-controlled antlions as friendly when their server
  m_hFollowTarget is set.
- Resolve m_Relationship/m_hFollowTarget datamap offsets and log them.
