ESP: classify NPC damage immunity/armour/vulnerability

- Resolve server m_takedamage (DAMAGE_NO/DAMAGE_EVENTS_ONLY = immune).
- Classify gunship/strider/dropship as ARMORED (OnTakeDamage only accepts
  DMG_BLAST; only the RPG passes), and headcrab/antlion/manhack as VULN
  (gravity gun / physics impact).
- ESP draws ARMORED/VULN/IMMUNE tags above the name (new "Damage tags"
  toggle, [esp] dmg).
- Aimbot, silent aim, triggerbot and melee skip immune targets and armoured
  targets unless the active weapon is the RPG.
