Avoid hinting against a non-unique hidden board

Because this clue set has multiple valid 5x5 completions, comparing every marked cell to the single hard-coded solution is not a reliable correctness test. A player can complete an alternate board that satisfies all 25 clues; clicking Hint then enters this branch, overwrites the first cell that differs from the hidden board, and turns the previously solved board into one with clue errors. Please either choose a uniquely solvable mosaic or reveal only cells that are forced by the current clues.
