game/rendering: play SpellCast animation during SMSG_SPELL_START

Browse source 
Add SpellCastAnimCallback to GameHandler, triggered on SMSG_SPELL_START
(start=true) and cleared on SMSG_SPELL_GO / SMSG_SPELL_FAILURE
(start=false) for both the player and other units.

Connect the callback in Application to play animation 3 (SpellCast) on
the player character, NPCs, and other players when they begin a cast.
The cast animation is one-shot (loop=false) so it auto-returns to Stand
when complete via the existing return-to-idle logic.

Also fire stop-cast on spell failure to cancel any stuck cast pose.
