Fixes mirrored slice exports by making orientation explicit: - PhotoSlice.swapped flag persists a user left/right swap - swap_left_right() mirrors [TL,TR,BR,BL] -> [TR,TL,BL,BR] - normalize_top_left() honors the flag so squarize/reset_rotation no longer overwrite manual orientation - Swap L/R toolbar button wired through canvas state + controller - Color-code left (orange) vs right (cyan) corners and edges
