fix: correct sync Warden MODULE check returning 0x01 instead of 0x00

The sync path's MODULE handler was returning 0x01 (module found) for
unwanted cheat DLLs (WPESPY, TAMIA, PRXDRVPE, etc.) instead of 0x00
(not found). Since VMaNGOS compares the result as a boolean, returning
any non-zero value for a cheat module tells the server "this cheat DLL
is loaded," triggering Warden penalties that accumulate into a kick
after ~3-5 minutes.

Also adds ±4KB hint window search to searchCodePattern for faster
PAGE_A resolution without full brute-force, and restores the turtle
PAGE_A fallback (confirmed patterns are runtime-patched offsets not
present in the on-disk PE).
