Example: sp_encoder1..7 force an immediate resend (no slap needed)

The encoder demos register a uniform spoof, but CS2 only re-transmits a field
when it actually changes, so the fake didn't appear until something moved the
value (e.g. a slap). Add ForceResendAll: after SetUniform, mark the field dirty
on every real player via IBaseEntity.NetworkStateChanged so it re-transmits on
the next snapshot and the uniform encoder hook fakes it immediately — entirely
from the plugin. Routes to the controller for CCSPlayerController fields, the
pawn otherwise. Skips bots/HLTV (no screen, never sent snapshots).
