Items: read ammo and inventory from the server arrays

The client m_iAmmo/m_hMyWeapons recv props still do not resolve, but the
listen server has the same CBaseCombatCharacter arrays in its datamap. Resolve
m_iAmmo and m_hMyWeapons there:
- reserve ammo comes from server_player_ammo() when the client array is
  missing, so full-ammo filtering works (RPG rockets at 3);
- the owned-weapon mask is filled from the server m_hMyWeapons[48] handles,
  so fallen weapons count as ammo before the player equips them.
Widen the datamap field-size filter to 512 for the 192-byte handle array.
