Example: revert to real values on sp_encoders_off + fix Reply crash

sp_encoders_off only unhooked, so clients kept showing the last fake value
(static fields aren't re-sent until they change). Force a resend of each field
AFTER unhooking so the real value goes back out and every client reverts
immediately.

Fix Reply(): it printed via pawn.Print, which routes through the pawn's
controller and throws "Controller is null" for console/RCON invocations or
unlinked pawns. Print at the client level (issuer.Print) with a log fallback
for console (null issuer) or any print failure.

Also clarify enc3 reply text (m_angEyeAngles fakes a player's look/camera
direction, seen by spectating them).
