Item ESP: tag world weapons, name ammo types, restrict crates

- Add a Weapons category and classify world weapon models (crowbar, pistol,
  revolver, SMG, AR2, shotgun, crossbow, RPG, grenade, gravity gun, stunstick,
  bugbait, sniper). Skip the active weapon and anything with a valid
  m_hOwner/m_hOwnerEntity handle so held weapons do not tag.
- Label ammo by model: pistol, SMG, AR2, .357, crossbow, shotgun, sniper,
  flares, AR2 grenade, RPG rocket and specific ammo-crate variants.
- Only item_item_crate and item_beacon_crate are supply crates; generic
  breakable crates are no longer tagged. Crate chunks stay excluded.
- Add item diagnostics: category state, prop-like entities with class/model/
  kind/distance/origin, and every item crate seen.
