Subject: [PATCH] Fix vanilla Warden check parsing and crypto reset

Vanilla PAGE_A/B checks are 24 bytes (no addr+len), PROC checks are
25 bytes (no second strIdx+offset), unlike WotLK's 29/30. Wrong sizes
caused incomplete responses with bad checksums, silently blocking
character creation on Turtle WoW.
