SetOfficialTarget
SetOfficialTarget merges entries into the free-to-place design -- owner-only, additive rather than replacing. Registering the full ~800-cell logo costs real storage deposit (measured ~0.19 GNOT/cell on testnet), enough that doing it in one transaction risks needing the whole amount upfront in a single call; additive means it can be split across as many affordable calls as needed, called repeatedly over time. encoded is "x,y,c;x,y,c;...", matching the CSV-ish convention already used by TopPlacers. Calling this with a coordinate already in the target just overwrites that one entry's color, same as you'd expect.
