B161 - Anti-Spam and Rockhound Repurchaseable

B161 makes Anti-Spam Software (0x33) and Rockhound Certificate (0x10A) independently repurchaseable in every patched executable, including saves where the persisted effect flag has already been cleared. Active rows use the zero-price removal route; inactive rows use the native purchase price/effect path.\n\nStatic/source/package validation passed. Live purchase, effect, save/reload, and player QA remain required.
