Fix CodeQL weak-crypto suppressions: switch lgtm to codeql inline format

The old `// lgtm [cpp/...]` comments used a space (invalid syntax) and
were placed on preceding lines rather than inline with the flagged code.
GitHub's CodeQL action v3 requires `// codeql[query-id]` on the same
line as the flagged expression. All four alert sites updated:

- world_socket.cpp: encryptCipher/decryptCipher.init() (protocol RC4)
- warden_module.cpp: decryptRC4() call (Warden protocol RC4)
- warden_crypto.cpp: initRC4() calls (Warden stream cipher init)
- game_handler.cpp: wardenLoadedModule_->load() (MD5+RC4 via Warden)

All uses are protocol-mandated by Blizzard's WoW/Warden spec and cannot
be replaced without breaking server interoperability.
