Handles: use the 11-bit networked EHANDLE entity index

The client m_hActiveWeapon is a networked EHANDLE: low 11 bits are the
entity index and the rest is the serial. Masking with 0xFFFF included serial
bits, so on later maps the weapon index became garbage (e.g. 49184/12319)
and melee killbot could not recognize the crowbar. Use 0x7FF for client and
server active-weapon handles, weapon owner checks and item-ESP weapon skips.
Document the layout in CONTEXT.
