Several handlers used packet fields as array indices or SQL column names without bounds checking, allowing crafted packets to panic the server or produce malformed SQL. Panic fixes (high severity): - handlers_mail: bounds check AccIndex against mailList length - handlers_misc: validate ArmourID >= 10000 and MogType <= 4 - handlers_mercenary: check RawDataPayload length before slicing - handlers_house: check RawDataPayload length in SaveDecoMyset - handlers_register: guard empty RawDataPayload in OperateRegister SQL column name fixes (medium severity): - handlers_misc: early return on unknown PointType - handlers_items: reject unknown StampType in weekly stamp handlers - handlers_achievement: cap AchievementID at 32 - handlers_goocoo: skip goocoo.Index > 4 - handlers_house: cap BoxIndex for warehouse operations - handlers_tower: fix MissionIndex=0 bypassing normalization guard
