feat: add PROC_TRIGGER floating combat text for spell procs

Browse source 
Handles SMSG_SPELL_CHANCE_PROC_LOG (previously silently ignored) to
display gold "PROC!" floating text when the player triggers a spell
proc. Reads caster/target packed GUIDs and spell ID from the packet
header; skips variable-length effect payload.

Adds CombatTextEntry::PROC_TRIGGER type with gold color rendering,
visible alongside existing damage/heal/energize floating numbers.
